Safety Note!

For safety reasons, the use of the apothecary

system is discouraged. Use the metric system

instead.

Avoirdupois System

Table 5.6

- In reality, an avoirdupois ounce actually

contains 28.34952 g however, we often round up

to 30 g. It is common practice to use 454 g as

the equivalent for a pound (28.35 g 16 oz/lb

453.6 g/lb, rounded to 454 g/lb).

Household Measure Volume

Table 5.7

- In reality, 1 fl oz (household measure)

contains less than 30 mL however, 30 mL is

usually used. When packaging a pint, companies

will typically present 473 mL, rather than the

full 480 mL, thus saving money over time.

- When something is divided into parts, each part

is considered a fraction of the whole. - If a pie is cut into 8 slices, one slice can be

expressed as 1/8, or one piece (1) of the whole

(8).

Terminology

numerator

the number on the upper part of a fraction

Terminology

denominator

the number on the bottom part of a fraction

Fractions

A fraction with the same numerator and same

denominator has a value equivalent to 1. In

other words, if you have 8 pieces of a pie that

has been cut into 8 pieces, you have 1 pie.

Discussion

- What are the distinguishing characteristics of

the following - proper fraction
- improper fraction
- mixed number

Remember

The symbol gt means is greater than. The

symbol gt means is less than.

Terminology

proper fraction

- a fraction with a value of less than 1
- a fraction with a numerator value smaller than

the denominators value

Terminology

improper fraction

- a fraction with a value of larger than 1
- a fraction with a numerator value larger than the

denominators value

Terminology

mixed number

a whole number and a fraction

Adding or Subtracting Fractions

- When adding or subtracting fractions with unlike

denominators, it is necessary to create a common

denominator.

Adding or Subtracting Fractions

- When adding or subtracting fractions with unlike

denominators, it is necessary to create a common

denominator. - This is like making both fractions into the same

kind of pie.

Terminology

common denominator

a number into which each of the unlike

denominators of two or more fractions can be

divided evenly

Remember

Multiplying a number by 1 does not change the

value of the number. Therefore, if you

multiply a fraction by a fraction that equals 1

(such as 5/5), you do not change the value of a

fraction.

Guidelines for Finding a Common Denominator

- Examine each denominator in the given fractions

for its divisors, or factors.

Guidelines for Finding a Common Denominator

- Examine each denominator in the given fractions

for its divisors, or factors. - See what factors any of the denominators have in

common.

Guidelines for Finding a Common Denominator

- Examine each denominator in the given fractions

for its divisors, or factors. - See what factors any of the denominators have in

common. - Form a common denominator by multiplying all the

factors that occur in all of the denominators. If

a factor occurs more than once, use it the

largest number of times it occurs in any

denominator.

Example 1 Find the least common denominator of

the following fractions

Step 1. Find the prime factors (numbers divisible

only by 1 and themselves) of each denominator.

Make a list of all the different prime factors

that you find. Include in the list each different

factor as many times as the factor occurs for any

one of the denominators of the given

fractions. The prime factors of 28 are 2, 2, and

7 (because 2 3 2 3 7 5 28). The prime factors of

6 are 2 and 3 (because 2 3 3 5 6). The number 2

occurs twice in one of the denominators, so it

must occur twice in the list. The list will also

include the unique factors 3 and 7 so the final

list is 2, 2, 3, and 7.

Example 1 Find the least common denominator of

the following fractions

Step 2. Multiply all the prime factors on your

list. The result of this multiplication is the

least common denominator.

Example 1 Find the least common denominator of

the following fractions

Step 3. To convert a fraction to an equivalent

fraction with the common denominator, first

divide the least common denominator by the

denominator of the fraction, then multiply both

the numerator and denominator by the result (the

quotient). The least common denominator of 9/28

and 1/6 is 84. In the first fraction, 84 divided

by 28 is 3, so multiply both the numerator and

the denominator by 3.

Example 1 Find the least common denominator of

the following fractions

In the second fraction, 84 divided by 6 is 14, so

multiply both the numerator and the denominator

by 14.

Example 1 Find the least common denominator of

the following fractions

The following are two equivalent fractions

Example 1 Find the least common denominator of

the following fractions

Step 4. Once the fractions are converted to

contain equal denominators, adding or subtracting

them is straightforward. Simply add or subtract

the numerators.

Multiplying Fractions

When multiply fractions, multiply the numerators

by numerators and denominators by denominators.

Multiplying Fractions

When multiply fractions, multiply the numerators

by numerators and denominators by

denominators. In other words, multiply all

numbers above the line then multiply all numbers

below the line.

Multiplying Fractions

When multiply fractions, multiply the numerators

by numerators and denominators by

denominators. In other words, multiply all

numbers above the line then multiply all numbers

below the line. Cancel if possible and reduce to

lowest terms.

Discussion

What happens to the value of a fraction when you

multiply the numerator and denominator by the

same number Answer The value of the fraction

does not change because you have multiplied the

original fraction by 1.

Multiplying Fractions

Dividing the denominator by a number is the same

as multiplying the numerator by that number.

Multiplying Fractions

Dividing the numerator by a number is the same as

multiplying the denominator by that number.

Dividing Fractions

To divide by a fraction, multiply by its

reciprocal, and then reduce it if necessary.

Terms to Remember

The Arabic System

The Arabic system is also called the decimal

system.

Terminology

indicate a quantity, fractions, and decimals.

Uses the numerals 0, 1, 2, 3, 4, 5, 6, 7, 8, 9.

The Arabic System

- The decimal serves as the anchor.
- Each place to the left of the decimal point

signals a tenfold increase. - Each place to the right signals a tenfold

decrease.

Decimal Units and Values

Terminology

place value

that describes the numerals relationship to the

decimal point

Terminology

leading zero

a zero that is placed to the left of the decimal

point, in the ones place, in a number that is

less than zero and is being represented by a

decimal value

Decimals

- A decimal is a fraction in which the denominator

is 10 or some multiple of 10. - Numbers written to the right of decimal point lt

1. - Numbers written to the left of the decimal point

gt 1

Example 2 Multiply the two given fractions.

Terminology

decimal

a fraction value in which the denominator is 10

or some multiple of 10

Remember

- Numbers to the left of the decimal point are

whole numbers. - Numbers to the right of the decimal point are

decimal fractions (part of a whole).

Decimal Places

Decimals

- Adding or Subtracting Decimals
- Place the numbers in columns so that the decimal

points are aligned directly under each other. - Add or subtract from the right column to the left

column.

Decimals

- Multiplying Decimals
- Multiply two decimals as whole numbers.
- Add the total number of decimal places that are

in the two numbers being multiplied. - Count that number of places from right to left in

the answer, and insert a decimal point.

Decimals

- Dividing Decimals
- Change both the divisor and dividend to whole

numbers by moving their decimal points the same

number of places to the right. - divisor number doing the dividing, the

denominator - dividend number being divided, the numerator
- If the divisor and the dividend have different

number of digits after the decimal point, choose

the one that has more digits and move its decimal

point a sufficient number of places to make it a

whole number.

Decimals

- Dividing Decimals
- 3. Move the decimal point in the other number the

same number of places, adding zeros at the end if

necessary. - Move the decimal point in the dividend the same

number of places, adding a zero at the end.

Decimals

- Rounding Decimals
- Rounding numbers is essential for accuracy.
- It may not be possible to measure a very small

quantity such as a hundredth of a milliliter. - A volumetric dose is commonly rounded to the

nearest tenth. - A solid dose is commonly rounded to the hundredth

or thousandth place, pending the accuracy of the

measuring device.

Decimals

- Rounding to the Nearest Tenth
- Carry the division out to the hundredth place
- If the hundredth place number 5, 1 to the

tenth place - If the hundredth place number 5, round the

number down by omitting the digit in the

hundredth place - 5.65 becomes 5.7 4.24 becomes 4.2

Discussion

When a number that has been rounded to the tenth

place is multiplied or divided by a number that

was rounded to the hundredth or thousandth place,

the resultant answer must be rounded back to the

tenth place. Why

Discussion

When a number that has been rounded to the tenth

place is multiplied or divided by a number that

was rounded to the hundredth or thousandth place,

the resultant answer must be rounded back to the

tenth place. Why Answer The answer can only be

accurate to the place to which the highest

rounding was made in the original numbers.

Decimals

- In most cases, a zero occurring at the end of a

digits is not written. - Do not drop the zero when the last digit

resulting from rounding is a zero. Such a zero is

considered significant to that particular problem

or dosage.

Numerical Ratios

- Ratios represent the relationship between
- two parts of the whole
- one part to the whole

Numerical Ratios
