641.52 is what percent of 792 - 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 792 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 792, so we can write it down as 100%=792.
4. We know, that x% equals 641.52 of the output value, so we can write it down as x%=641.52.
5. Now we have two simple equations:
1) 100%=792
2) x%=641.52
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%=792/641.52
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 641.52 is what percent of 792

100%/x%=792/641.52
(100/x)*x=(792/641.52)*x       - we multiply both sides of the equation by x
100=1.2345679012346*x       - we divide both sides of the equation by (1.2345679012346) to get x
100/1.2345679012346=x
81=x
x=81

now we have:
641.52 is 81% of 792
