Question

Elena ate 2/8 of a pizza and Dylan ate 1/5. Use the number lines and benchmark fractions to estimate how much of the pizza they ate. Explain

Answer 1

18/40

Explanation:

1. Find a common denominator

8, 16, 24, 32, 40

5, 10, 15, 20, 25, 30, 35, 40

2/8 times 5= 10/40

1/5 times 8= 8/40

10/40 plus 8/40= 18/40
