62.5 is what percent of 398 - 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 398 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 398, so we can write it down as 100%=398.
4. We know, that x% equals 62.5 of the output value, so we can write it down as x%=62.5.
5. Now we have two simple equations:
1) 100%=398
2) x%=62.5
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%=398/62.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 62.5 is what percent of 398

100%/x%=398/62.5
(100/x)*x=(398/62.5)*x       - we multiply both sides of the equation by x
100=6.368*x       - we divide both sides of the equation by (6.368) to get x
100/6.368=x
15.70351758794=x
x=15.70351758794

now we have:
62.5 is 15.70351758794% of 398
