10.87 is what percent of 53.76 - 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 53.76 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 53.76, so we can write it down as 100%=53.76.
4. We know, that x% equals 10.87 of the output value, so we can write it down as x%=10.87.
5. Now we have two simple equations:
1) 100%=53.76
2) x%=10.87
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%=53.76/10.87
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 10.87 is what percent of 53.76

100%/x%=53.76/10.87
(100/x)*x=(53.76/10.87)*x       - we multiply both sides of the equation by x
100=4.9457221711132*x       - we divide both sides of the equation by (4.9457221711132) to get x
100/4.9457221711132=x
20.219494047619=x
x=20.219494047619

now we have:
10.87 is 20.219494047619% of 53.76
