63 is what percent of 635 - 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 635 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 635, so we can write it down as 100%=635.
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%=635
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%=635/63
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 635

100%/x%=635/63
(100/x)*x=(635/63)*x       - we multiply both sides of the equation by x
100=10.079365079365*x       - we divide both sides of the equation by (10.079365079365) to get x
100/10.079365079365=x
9.9212598425197=x
x=9.9212598425197

now we have:
63 is 9.9212598425197% of 635
