13.35 is what percent of 20.2 - 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 20.2 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 20.2, so we can write it down as 100%=20.2.
4. We know, that x% equals 13.35 of the output value, so we can write it down as x%=13.35.
5. Now we have two simple equations:
1) 100%=20.2
2) x%=13.35
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%=20.2/13.35
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 13.35 is what percent of 20.2

100%/x%=20.2/13.35
(100/x)*x=(20.2/13.35)*x       - we multiply both sides of the equation by x
100=1.5131086142322*x       - we divide both sides of the equation by (1.5131086142322) to get x
100/1.5131086142322=x
66.089108910891=x
x=66.089108910891

now we have:
13.35 is 66.089108910891% of 20.2
