13557 is what percent of 20788 - 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 20788 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 20788, so we can write it down as 100%=20788.
4. We know, that x% equals 13557 of the output value, so we can write it down as x%=13557.
5. Now we have two simple equations:
1) 100%=20788
2) x%=13557
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%=20788/13557
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 13557 is what percent of 20788

100%/x%=20788/13557
(100/x)*x=(20788/13557)*x       - we multiply both sides of the equation by x
100=1.5333775909124*x       - we divide both sides of the equation by (1.5333775909124) to get x
100/1.5333775909124=x
65.21550894747=x
x=65.21550894747

now we have:
