543.2 is what percent of 625 - 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 625 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 625, so we can write it down as 100%=625.
4. We know, that x% equals 543.2 of the output value, so we can write it down as x%=543.2.
5. Now we have two simple equations:
1) 100%=625
2) x%=543.2
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%=625/543.2
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 543.2 is what percent of 625

100%/x%=625/543.2
(100/x)*x=(625/543.2)*x       - we multiply both sides of the equation by x
100=1.15058910162*x       - we divide both sides of the equation by (1.15058910162) to get x
100/1.15058910162=x
86.912=x
x=86.912

now we have:
543.2 is 86.912% of 625
