85.12 is what percent of 89.6 - 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 89.6 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 89.6, so we can write it down as 100%=89.6.
4. We know, that x% equals 85.12 of the output value, so we can write it down as x%=85.12.
5. Now we have two simple equations:
1) 100%=89.6
2) x%=85.12
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%=89.6/85.12
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 85.12 is what percent of 89.6

100%/x%=89.6/85.12
(100/x)*x=(89.6/85.12)*x       - we multiply both sides of the equation by x
100=1.0526315789474*x       - we divide both sides of the equation by (1.0526315789474) to get x
100/1.0526315789474=x
95=x
x=95

now we have:
85.12 is 95% of 89.6
