63 is what percent of 915 - 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 915 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 915, so we can write it down as 100%=915.
4. We know, that x% equals 63 of the output value, so we can write it down as x%=63.
5. Now we have two simple equations:
1) 100%=915
2) x%=63
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%=915/63
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 63 is what percent of 915

100%/x%=915/63
(100/x)*x=(915/63)*x       - we multiply both sides of the equation by x
100=14.52380952381*x       - we divide both sides of the equation by (14.52380952381) to get x
100/14.52380952381=x
6.8852459016393=x
x=6.8852459016393

now we have:
63 is 6.8852459016393% of 915
