45.2 is what percent of 131 - 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 131 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 131, so we can write it down as 100%=131.
4. We know, that x% equals 45.2 of the output value, so we can write it down as x%=45.2.
5. Now we have two simple equations:
1) 100%=131
2) x%=45.2
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%=131/45.2
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 45.2 is what percent of 131

100%/x%=131/45.2
(100/x)*x=(131/45.2)*x       - we multiply both sides of the equation by x
100=2.8982300884956*x       - we divide both sides of the equation by (2.8982300884956) to get x
100/2.8982300884956=x
34.503816793893=x
x=34.503816793893

now we have:
45.2 is 34.503816793893% of 131
