John and Peter share $180 in the ratio 3 : 2. How much more money does John receive than Peter?

In order to solve this problem,

Add the Number in the Ratio together

3+2=5

In the problem it tells you that the combined money is 180

Let x be the "1" in the ratio

Divide to find x

5x=180

5x:5 = 180:5

x=36

So now you know how much "1" is

John = 3*36 = 108

Peter = 2*36 = 72

108-72

The answer is 36
