20.12 is what percent of 148.5 - 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 148.5 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 148.5, so we can write it down as 100%=148.5.
4. We know, that x% equals 20.12 of the output value, so we can write it down as x%=20.12.
5. Now we have two simple equations:
1) 100%=148.5
2) x%=20.12
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%=148.5/20.12
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 20.12 is what percent of 148.5

100%/x%=148.5/20.12
(100/x)*x=(148.5/20.12)*x       - we multiply both sides of the equation by x
100=7.3807157057654*x       - we divide both sides of the equation by (7.3807157057654) to get x
100/7.3807157057654=x
13.548821548822=x
x=13.548821548822

now we have:
20.12 is 13.548821548822% of 148.5
