8.31 is what percent of 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 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 75, so we can write it down as 100%=75.
4. We know, that x% equals 8.31 of the output value, so we can write it down as x%=8.31.
5. Now we have two simple equations:
1) 100%=75
2) x%=8.31
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%=75/8.31
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 8.31 is what percent of 75

100%/x%=75/8.31
(100/x)*x=(75/8.31)*x       - we multiply both sides of the equation by x
100=9.0252707581227*x       - we divide both sides of the equation by (9.0252707581227) to get x
100/9.0252707581227=x
11.08=x
x=11.08

now we have:
8.31 is 11.08% of 75
