73.2 is what percent of 120 - step by step solution

To get the solution, we are looking for, we need to point out what we know.

1. We assume, that the number 120 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 100% equals 120, so we can write it down as 100%=120.
4. We know, that x% equals 73.2 of the output value, so we can write it down as x%=73.2.
5. Now we have two simple equations:
1) 100%=120
2) x%=73.2
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
100%/x%=120/73.2
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 73.2 is what percent of 120

100%/x%=120/73.2
(100/x)*x=(120/73.2)*x       - we multiply both sides of the equation by x
100=1.6393442622951*x       - we divide both sides of the equation by (1.6393442622951) to get x
100/1.6393442622951=x
61=x
x=61

now we have:
73.2 is 61% of 120
