130.5 is what percent of 142.25 - 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 142.25 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 142.25, so we can write it down as 100%=142.25.
4. We know, that x% equals 130.5 of the output value, so we can write it down as x%=130.5.
5. Now we have two simple equations:
1) 100%=142.25
2) x%=130.5
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%=142.25/130.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 130.5 is what percent of 142.25

100%/x%=142.25/130.5
(100/x)*x=(142.25/130.5)*x       - we multiply both sides of the equation by x
100=1.0900383141762*x       - we divide both sides of the equation by (1.0900383141762) to get x
100/1.0900383141762=x
91.739894551845=x
x=91.739894551845

now we have:
130.5 is 91.739894551845% of 142.25
