128.25 is what percent of 327 - 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 327 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 327, so we can write it down as 100%=327.
4. We know, that x% equals 128.25 of the output value, so we can write it down as x%=128.25.
5. Now we have two simple equations:
1) 100%=327
2) x%=128.25
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%=327/128.25
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 128.25 is what percent of 327

100%/x%=327/128.25
(100/x)*x=(327/128.25)*x       - we multiply both sides of the equation by x
100=2.5497076023392*x       - we divide both sides of the equation by (2.5497076023392) to get x
100/2.5497076023392=x
39.220183486239=x
x=39.220183486239

now we have:
128.25 is 39.220183486239% of 327
