128.6 is what percent of 132.75 - 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 132.75 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 132.75, so we can write it down as 100%=132.75.
4. We know, that x% equals 128.6 of the output value, so we can write it down as x%=128.6.
5. Now we have two simple equations:
1) 100%=132.75
2) x%=128.6
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%=132.75/128.6
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 128.6 is what percent of 132.75

100%/x%=132.75/128.6
(100/x)*x=(132.75/128.6)*x       - we multiply both sides of the equation by x
100=1.0322706065319*x       - we divide both sides of the equation by (1.0322706065319) to get x
100/1.0322706065319=x
96.873822975518=x
x=96.873822975518

now we have:
128.6 is 96.873822975518% of 132.75
