Lesson 10 Rational Numbers and Equivalent Fractions

6
Sets of Numbers Counting Numbers- Whole Numbers- Integers- Rational Numbers- fractions and decimals (Show on a number line)

7
Equivalent Fraction Different ways to name the same amount. (Use fraction bars to illustrate)

8
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.

9
Examples Find the GCF of: – 12 and 15 – 24 and 12 – 30 and 10

10
Using Prime Factorization to Reduce 72/108 50/100
