72.8 is what percent of 40.32 - 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 40.32 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 40.32, so we can write it down as 100%=40.32.
4. We know, that x% equals 72.8 of the output value, so we can write it down as x%=72.8.
5. Now we have two simple equations:
1) 100%=40.32
2) x%=72.8
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%=40.32/72.8
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 72.8 is what percent of 40.32

100%/x%=40.32/72.8
(100/x)*x=(40.32/72.8)*x       - we multiply both sides of the equation by x
100=0.55384615384615*x       - we divide both sides of the equation by (0.55384615384615) to get x
100/0.55384615384615=x
180.55555555556=x
x=180.55555555556

now we have:
72.8 is 180.55555555556% of 40.32
