631.71 is what percent of 875 - 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 875 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 875, so we can write it down as 100%=875.
4. We know, that x% equals 631.71 of the output value, so we can write it down as x%=631.71.
5. Now we have two simple equations:
1) 100%=875
2) x%=631.71
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%=875/631.71
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 631.71 is what percent of 875

100%/x%=875/631.71
(100/x)*x=(875/631.71)*x       - we multiply both sides of the equation by x
100=1.3851292523468*x       - we divide both sides of the equation by (1.3851292523468) to get x
100/1.3851292523468=x
72.195428571429=x
x=72.195428571429

now we have:
631.71 is 72.195428571429% of 875
