7.25 is what percent of 40.5 - 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 40.5 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 40.5, so we can write it down as 100%=40.5.
4. We know, that x% equals 7.25 of the output value, so we can write it down as x%=7.25.
5. Now we have two simple equations:
1) 100%=40.5
2) x%=7.25
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%=40.5/7.25
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 7.25 is what percent of 40.5

100%/x%=40.5/7.25
(100/x)*x=(40.5/7.25)*x       - we multiply both sides of the equation by x
100=5.5862068965517*x       - we divide both sides of the equation by (5.5862068965517) to get x
100/5.5862068965517=x
17.901234567901=x
x=17.901234567901

now we have:
7.25 is 17.901234567901% of 40.5
