Question

Ben ate 3/5 of the sandwich and his sister ate 1/7 of the sandwich. What is the best estimate of how much Benjamin ate than his sister?

Answer 1

Explanation:

LCD = 35

Ben: 3/5 = 21/35

Sister: 1/7 = 5/35

The whole sandwich = 35/35

Ben ate 21/35

Sister ate 5/35

9/35 remain

21/5 = 4.2

Ben ate 4.2 times more of the sandwich than his sister
