13.1 is what percent of 62.64 - 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 62.64 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 62.64, so we can write it down as 100%=62.64.
4. We know, that x% equals 13.1 of the output value, so we can write it down as x%=13.1.
5. Now we have two simple equations:
1) 100%=62.64
2) x%=13.1
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%=62.64/13.1
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 13.1 is what percent of 62.64

100%/x%=62.64/13.1
(100/x)*x=(62.64/13.1)*x       - we multiply both sides of the equation by x
100=4.781679389313*x       - we divide both sides of the equation by (4.781679389313) to get x
100/4.781679389313=x
20.913154533844=x
x=20.913154533844

now we have:
13.1 is 20.913154533844% of 62.64
