Question

Jesse saved one half of what he made last week. Zoie made $60 and saved an equivalent ratio to what Jesse saved. How much did Zoie save?

Answer 1

You could also consider the problem this way:

 

Jesse saved half of what he made.

Zoie saved the same ratio, which means she also saved half of what she made.

Zoie made $60, and she saved half.

Half of $60 is $30.

Answer 2

Let amount Jesse made last week = X 

Jesse saved half of X = X/2 

 

So ratio of Amount_made : Amount_saved = x : x/2 ie 2:1

 

Zoie made $60. 

Zoie has an equivalent ratio to that of Jesse. 

Let Y = amount Zoie saved

then 60:Y = 2:1 

ie. 60/Y = 2/1

so Y = 60/2 = 30

 

Zoie saved $30
