Title: MATH 6 Intro to Fractions!

1
MATH 6 Intro to Fractions!
• Anatomy of the fraction...
• Numerator
• Denominator
• Name the different types of fractions
• The term above the line in a fraction. The
numerator tells how many parts are being talked
• The number below the line in a fraction. The
denominator indicates what kind or size of parts
the numerator counts.
• Improper
• Proper
• Mixed Numbers

2
What are Fractions?
• Name the operation happening between the
numerator and the denominator in a fraction.
• Division!
• Therefore when we name a fraction like 3/4, we
would say
• three fourths
• three out of 4
• three divided by four
• 34
• Three to Four

3
Proper Fractions
• Proper Fractions
• Simplifying Proper Fractions
• Fractions where the numerator is less than the
denominator
• The value is less than one.
• Find the largest number you can divide into BOTH
numerator and denominator (also known as the
GCF).

4
Examples of SimplifyingProper Fraction
• Example 1
• Simplify 6/8.
• What is the GCF?
• Divide both numerator and denominator by the GCF.

5
Simplifying Proper Fractions
• Examples 2 and 3
• Simplify 9/15
• Simplify 6/20
• Divide numerator and denominator by the GCF.
• Solutions
• 9/15 3/5
• 6/20 3/10

6
Examples of SimplifyingProper Fraction
• Example 2
• Simplify 12/36
• What is the GCF?
• Divide both numerator and denominator by the GCF.

7
Improper Fractions
• Improper Fractions
• Converting Improper Fractions into Mixed Numbers
• Fractions where the numerator is LARGER THAN the
denominator.
• The value is greater than or equal to 1.
• Divide the numerator by the denominator.
• The remainder (if there is one) becomes the
numerator of the mixed number.

8
Converting Improper Fractions into Mixed Numbers
• Improper Fractions to Mixed Numbers
• Example 1
• What kind of fraction is 26/5?
• Improper fractions in simplest form do NOT have a
GCF and we can turn them into mixed numbers
• Divide numerator 26 by denominator 5
• 26 ? 5 5
• Remainder is 1

9
Converting Mixed Numbers to Improper Fractions
• Mixed Number
• Changing a mixed number into an improper fraction
• The sum of WHOLE NUMBER and a PROPER FRACTION.
• 2 3/4 2 3/4
• 3 1/4 3 1/4
• Multiply the whole number by the denominator.
• Add the numerator to this product.
• Denominator stays the same

10
Converting Mixed Numbers to Improper Fractions
• Example 1
• 4 3/4
• Multiply the whole number by the denominator
• 4 x 4 16
• Now, add the numerator to this product and the
denominator stays the same
• 16 3 19

11
Converting Mixed Numbers to Improper Fractions
Examples
• Example 2
• 2 4/5
• Example 3
• 5 2/7
