9.12 is what percent of 68 - 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 68 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 68, so we can write it down as 100%=68.
4. We know, that x% equals 9.12 of the output value, so we can write it down as x%=9.12.
5. Now we have two simple equations:
1) 100%=68
2) x%=9.12
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%=68/9.12
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 9.12 is what percent of 68

100%/x%=68/9.12
(100/x)*x=(68/9.12)*x       - we multiply both sides of the equation by x
100=7.4561403508772*x       - we divide both sides of the equation by (7.4561403508772) to get x
100/7.4561403508772=x
13.411764705882=x
x=13.411764705882

now we have:
9.12 is 13.411764705882% of 68
