8.56 is what percent of 11.2 - 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 11.2 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 11.2, so we can write it down as 100%=11.2.
4. We know, that x% equals 8.56 of the output value, so we can write it down as x%=8.56.
5. Now we have two simple equations:
1) 100%=11.2
2) x%=8.56
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%=11.2/8.56
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 8.56 is what percent of 11.2

100%/x%=11.2/8.56
(100/x)*x=(11.2/8.56)*x       - we multiply both sides of the equation by x
100=1.3084112149533*x       - we divide both sides of the equation by (1.3084112149533) to get x
100/1.3084112149533=x
76.428571428571=x
x=76.428571428571

now we have:
8.56 is 76.428571428571% of 11.2
