11.57 is what percent of 12.928 - 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 12.928 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 12.928, so we can write it down as 100%=12.928.
4. We know, that x% equals 11.57 of the output value, so we can write it down as x%=11.57.
5. Now we have two simple equations:
1) 100%=12.928
2) x%=11.57
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%=12.928/11.57
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 11.57 is what percent of 12.928

100%/x%=12.928/11.57
(100/x)*x=(12.928/11.57)*x       - we multiply both sides of the equation by x
100=1.1173725151253*x       - we divide both sides of the equation by (1.1173725151253) to get x
100/1.1173725151253=x
89.495668316832=x
x=89.495668316832

now we have:
11.57 is 89.495668316832% of 12.928
