521.74 is what percent of 7200 - 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 7200 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 7200, so we can write it down as 100%=7200.
4. We know, that x% equals 521.74 of the output value, so we can write it down as x%=521.74.
5. Now we have two simple equations:
1) 100%=7200
2) x%=521.74
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%=7200/521.74
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 521.74 is what percent of 7200

100%/x%=7200/521.74
(100/x)*x=(7200/521.74)*x       - we multiply both sides of the equation by x
100=13.799977000038*x       - we divide both sides of the equation by (13.799977000038) to get x
100/13.799977000038=x
7.2463888888889=x
x=7.2463888888889

now we have:
521.74 is 7.2463888888889% of 7200
