Molly and Liza are exercising. Molly does 10 push-ups at the same time as Liza does 15 push-ups. When Molly does 40 push-ups, how many push-ups does Liza do

60 push-ups

Step-by-step explanation:

Set up a ratio to represent the problem:

Molly : Liza

10 : 15

40 : ?

How did we get from 10 to 40?

You multiply by 4. Therefore, multiply by 4 on both sides of the ratio.

10 : 15

x4   x4

40 : 60

So, Liza does 60 push-ups while Molly does 40.
