130.5 is what percent of 165 - 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 165 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 165, so we can write it down as 100%=165.
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%=165
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%=165/130.5
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 165

100%/x%=165/130.5
(100/x)*x=(165/130.5)*x       - we multiply both sides of the equation by x
100=1.264367816092*x       - we divide both sides of the equation by (1.264367816092) to get x
100/1.264367816092=x
79.090909090909=x
x=79.090909090909

now we have:
130.5 is 79.090909090909% of 165
