8.55 is what percent of 12.5 - 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 12.5 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 12.5, so we can write it down as 100%=12.5.
4. We know, that x% equals 8.55 of the output value, so we can write it down as x%=8.55.
5. Now we have two simple equations:
1) 100%=12.5
2) x%=8.55
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%=12.5/8.55
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 8.55 is what percent of 12.5

100%/x%=12.5/8.55
(100/x)*x=(12.5/8.55)*x       - we multiply both sides of the equation by x
100=1.4619883040936*x       - we divide both sides of the equation by (1.4619883040936) to get x
100/1.4619883040936=x
68.4=x
x=68.4

now we have:
8.55 is 68.4% of 12.5
