56 is what percent of 20815 - 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 20815 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 20815, so we can write it down as 100%=20815.
4. We know, that x% equals 56 of the output value, so we can write it down as x%=56.
5. Now we have two simple equations:
1) 100%=20815
2) x%=56
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%=20815/56
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 56 is what percent of 20815

100%/x%=20815/56
(100/x)*x=(20815/56)*x       - we multiply both sides of the equation by x
100=371.69642857143*x       - we divide both sides of the equation by (371.69642857143) to get x
100/371.69642857143=x
0.26903675234206=x
x=0.26903675234206

now we have:
56 is 0.26903675234206% of 20815
