85.57 is what percent of 103 - 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 103 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 103, so we can write it down as 100%=103.
4. We know, that x% equals 85.57 of the output value, so we can write it down as x%=85.57.
5. Now we have two simple equations:
1) 100%=103
2) x%=85.57
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%=103/85.57
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 85.57 is what percent of 103

100%/x%=103/85.57
(100/x)*x=(103/85.57)*x       - we multiply both sides of the equation by x
100=1.2036928830197*x       - we divide both sides of the equation by (1.2036928830197) to get x
100/1.2036928830197=x
83.077669902913=x
x=83.077669902913

now we have:
85.57 is 83.077669902913% of 103
