9.75 is what percent of 15.12 - 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 15.12 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 15.12, so we can write it down as 100%=15.12.
4. We know, that x% equals 9.75 of the output value, so we can write it down as x%=9.75.
5. Now we have two simple equations:
1) 100%=15.12
2) x%=9.75
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%=15.12/9.75
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 9.75 is what percent of 15.12

100%/x%=15.12/9.75
(100/x)*x=(15.12/9.75)*x       - we multiply both sides of the equation by x
100=1.5507692307692*x       - we divide both sides of the equation by (1.5507692307692) to get x
100/1.5507692307692=x
64.484126984127=x
x=64.484126984127

now we have:
9.75 is 64.484126984127% of 15.12
