Question

Mamie saved 161.25. This is 25% of the amount she needs to save. How much money does Mamie need to save?

Answer 1

All you need to do is multiply 161.25 X 4 = 625

How did I do that?
25% is 1/4 in fraction form, all you had to do is multiply it by four.

Answer 2

Since 25% is 1/4, we multiple 161.25 by 4/1 to get the answer of 645 for the goal to save.
