8 is what percent of 71.13 - 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 71.13 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 71.13, so we can write it down as 100%=71.13.
4. We know, that x% equals 8 of the output value, so we can write it down as x%=8.
5. Now we have two simple equations:
1) 100%=71.13
2) x%=8
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%=71.13/8
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 8 is what percent of 71.13

100%/x%=71.13/8
(100/x)*x=(71.13/8)*x       - we multiply both sides of the equation by x
100=8.89125*x       - we divide both sides of the equation by (8.89125) to get x
100/8.89125=x
11.247012512301=x
x=11.247012512301

now we have:
8 is 11.247012512301% of 71.13
