Rational Numbers and Equivalent Fractions
Lesson 10 Rational Numbers and Equivalent Fractions

Sets of Numbers Counting Numbers- Whole Numbers- Integers-
Rational Numbers- fractions and decimals (Show on a number line)

Equivalent Fraction Different ways to name the same amount.
(Use fraction bars to illustrate)

Greatest Common Factor
The greatest common factor of a set of numbers is the largest whole number that is a factor of every number in the set. We can reduce a fraction using the GCF. Use a multiplication chart to help you find the GCF of a set of numbers.

Examples Find the GCF of: 12 and 15 24 and 12 30 and 10

Using Prime Factorization to Reduce
72/108 50/100

Create an Equivalent Fraction
Fish hook Examples: Write a fraction equivalent to ½ that has a denominator of 100. ¾ that has a denominator of 12. 5/6 with a denominator of 24.

Comparing Fractions Change to a decimal 2/3 and 3/5 ¼ and 2/8

Improper Fractions Improper- 7/2, 4/4, 10/3, 12/6
Not Improper- 2/5, 1/8, 3/10, 6/12

Mixed Numbers A whole number and fraction 2 ¾ 1 ¼ 4 ½

Changing Improper to Mixed
(use fraction blocks) 5/2 6/3 4/4
