13.57 is what percent of 52.1 - 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 52.1 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 52.1, so we can write it down as 100%=52.1.
4. We know, that x% equals 13.57 of the output value, so we can write it down as x%=13.57.
5. Now we have two simple equations:
1) 100%=52.1
2) x%=13.57
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%=52.1/13.57
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 13.57 is what percent of 52.1

100%/x%=52.1/13.57
(100/x)*x=(52.1/13.57)*x       - we multiply both sides of the equation by x
100=3.8393515106853*x       - we divide both sides of the equation by (3.8393515106853) to get x
100/3.8393515106853=x
26.046065259117=x
x=26.046065259117

now we have:
13.57 is 26.046065259117% of 52.1
