Question

Can someone please so me how I would figure out how to do this? I believe it’s subtraction. But I’m not sure

Answer 1

A. 1/12.

Explanation:

Orville and Wilbur ate 1/3 + 1/4

= 4/12 + 3/12

= 7/12 of the pizza.

So there was 1 - 7/12 = 5/12 of the pizza left.

So Ruth ate 5/12 * 1/5

= 5/60

= 1/12.
