Simplifying Fractions 3-5

2
Lesson 1 – Equivalent Fractions I can use multiples to write equivalent fractions. I can use factors to write equivalent fractions. Warm Up – Define equivalent fractions. P. 151

3
Using Multiples Use multiples to write two fractions equivalent to 7/8. Multiply the numerator and the denominator by the SAME number & you have an equivalent fraction! Example: 7 x 2 = 147 x 3 = 21 8 x 2 = 168 x 3 = 24 71421 are equivalent fractions! 81624

4
Using Factors Example: Use factors to write two fractions equivalent to 24/30. Divide the numerator and the denominator by the SAME factor & you have an equivalent fraction! Example: 24 ÷ 2 = 12 24 ÷ 3 = 8 30 ÷ 2 15 30 ÷ 3 10 24 is equivalent to 12 8 3015 & 10

5
Finding Equivalent Fractions Use multiples to write two fractions equivalent to each fraction. 1) 52) 33) 2 6 8 9 Use factors to write two fractions equivalent to each fraction. 1) 182) 273) 60 36 81 140

6
Simplify by Dividing Divide the numerator and denominator by a common factor. Example: Simplify 12 24 What factor evenly divides into both 12 and 24? (Continue asking the same question until there are no remaining common factors, then your fraction is simplified.) 1) 242) 183) 25 32 27 35
