108.79 is what percent of 135 - 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 135 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 135, so we can write it down as 100%=135.
4. We know, that x% equals 108.79 of the output value, so we can write it down as x%=108.79.
5. Now we have two simple equations:
1) 100%=135
2) x%=108.79
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%=135/108.79
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 108.79 is what percent of 135

100%/x%=135/108.79
(100/x)*x=(135/108.79)*x       - we multiply both sides of the equation by x
100=1.2409228789411*x       - we divide both sides of the equation by (1.2409228789411) to get x
100/1.2409228789411=x
80.585185185185=x
x=80.585185185185

now we have:
108.79 is 80.585185185185% of 135
