131.66 is what percent of 2515 - 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 2515 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 2515, so we can write it down as 100%=2515.
4. We know, that x% equals 131.66 of the output value, so we can write it down as x%=131.66.
5. Now we have two simple equations:
1) 100%=2515
2) x%=131.66
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%=2515/131.66
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 131.66 is what percent of 2515

100%/x%=2515/131.66
(100/x)*x=(2515/131.66)*x       - we multiply both sides of the equation by x
100=19.102233024457*x       - we divide both sides of the equation by (19.102233024457) to get x
100/19.102233024457=x
5.2349900596421=x
x=5.2349900596421

now we have:
131.66 is 5.2349900596421% of 2515
