13.7 is what percent of 25.5 - 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 25.5 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 25.5, so we can write it down as 100%=25.5.
4. We know, that x% equals 13.7 of the output value, so we can write it down as x%=13.7.
5. Now we have two simple equations:
1) 100%=25.5
2) x%=13.7
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%=25.5/13.7
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 13.7 is what percent of 25.5

100%/x%=25.5/13.7
(100/x)*x=(25.5/13.7)*x       - we multiply both sides of the equation by x
100=1.8613138686131*x       - we divide both sides of the equation by (1.8613138686131) to get x
100/1.8613138686131=x
53.725490196078=x
x=53.725490196078

now we have:
13.7 is 53.725490196078% of 25.5
