1. Fractions Introduction and Review

2. Simplifying Fractions Divide the numerator (top) and denominator (bottom) by the same number Repeat, as needed 12 ÷ 2 = 6 ÷ 3 = 2 18 ÷ 2 9 ÷ 3 3or 12 ÷ 6 = 2 18 ÷ 6 3

3. Simplifying Fractions Simplify: 1) 20 2) 16 24 28 3) 25 4) 100 40 120

4. Equivalent Fractions Multiply OR Divide the numerator and denominator by the same number There are many equivalent fractions for every fraction given 4 2 = 8 4 3 = 12 5 2 10 5 3 15 4 11 = 44 4 20 = 80 5 11 55 5 20 100

5. Equivalent Fractions Find two equivalent fractions for each fraction shown: 1) 10 = = 2) 20 = = _____ 11 40 3) 3 = ____ = ____4) 9 = _____ = _____ 8 18

6. Improper Fractions The numerator is larger than the denominator It is still possible to simplify or find equivalent fractions: 8 ÷ 2 = 4 8 3 = 24 6 ÷ 2 3 6 3 18 Sometimes it is best to leave the improper fraction as it is; sometimes it should be changed into a Mixed Number
