- Can be parts of a whole number
- Can be added
- Can be Subtracted
- Can be multiplied
- Can be Divided

Fractions

- Fractions consist of two numbers. The top number

is called the . The bottom

number is called the

- numerator denominator

numerator

denominator.

Adding Fractions

- To add fractions with different denominators
- find the Least Common Denominator (LCD) of

the fractions - rename the fractions to have the LCD
- add the numerators of the fractions
- simplify the Fraction

- To add two fractions with the same denominator
- add the numerators place that sum over

the common denominator

Subtracting Fractions

- To subtract two fractions with the same

denominator - subtract the numerators
- place that difference over the common

denominator.

- To Subtract Fractions with different

denominators - Find the Lowest Common Denominator (LCD)

of the fractions - Rename the fractions to have the LCD
- Subtract the numerators of the

fractions The difference will be the numerator

and the LCD will be the denominator of the

answer. - Simplify the Fraction

Multiplying Fractions

- To Multiply Fractions
- Multiply the numerators of the fractions
- Multiply the denominators of the fractions
- Place the product of the numerators over the

product of the denominators - Simplify the Fraction

Dividing Fractions

- To Divide Fractions
- Invert (i.e. turn over) the denominator fraction

and multiply the fractions - Multiply the numerators of the fractions
- Multiply the denominators of the fractions

- Place the product of the numerators over the

product of the denominators - Simplify the Fraction
