53.1 is what percent of 132.8 - 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 132.8 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 132.8, so we can write it down as 100%=132.8.
4. We know, that x% equals 53.1 of the output value, so we can write it down as x%=53.1.
5. Now we have two simple equations:
1) 100%=132.8
2) x%=53.1
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%=132.8/53.1
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 53.1 is what percent of 132.8

100%/x%=132.8/53.1
(100/x)*x=(132.8/53.1)*x       - we multiply both sides of the equation by x
100=2.5009416195857*x       - we divide both sides of the equation by (2.5009416195857) to get x
100/2.5009416195857=x
39.984939759036=x
x=39.984939759036

now we have:
53.1 is 39.984939759036% of 132.8
