87 is what percent of 10824 - 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 10824 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 10824, so we can write it down as 100%=10824.
4. We know, that x% equals 87 of the output value, so we can write it down as x%=87.
5. Now we have two simple equations:
1) 100%=10824
2) x%=87
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%=10824/87
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 87 is what percent of 10824

100%/x%=10824/87
(100/x)*x=(10824/87)*x       - we multiply both sides of the equation by x
100=124.41379310345*x       - we divide both sides of the equation by (124.41379310345) to get x
100/124.41379310345=x
0.80376940133038=x
x=0.80376940133038

now we have:
87 is 0.80376940133038% of 10824
