64.8 is what percent of 519 - 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 519 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 519, so we can write it down as 100%=519.
4. We know, that x% equals 64.8 of the output value, so we can write it down as x%=64.8.
5. Now we have two simple equations:
1) 100%=519
2) x%=64.8
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%=519/64.8
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 64.8 is what percent of 519

100%/x%=519/64.8
(100/x)*x=(519/64.8)*x       - we multiply both sides of the equation by x
100=8.0092592592593*x       - we divide both sides of the equation by (8.0092592592593) to get x
100/8.0092592592593=x
12.485549132948=x
x=12.485549132948

now we have:
64.8 is 12.485549132948% of 519
