85.4 is what percent of 101.85 - 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 101.85 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 101.85, so we can write it down as 100%=101.85.
4. We know, that x% equals 85.4 of the output value, so we can write it down as x%=85.4.
5. Now we have two simple equations:
1) 100%=101.85
2) x%=85.4
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%=101.85/85.4
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 85.4 is what percent of 101.85

100%/x%=101.85/85.4
(100/x)*x=(101.85/85.4)*x       - we multiply both sides of the equation by x
100=1.1926229508197*x       - we divide both sides of the equation by (1.1926229508197) to get x
100/1.1926229508197=x
83.848797250859=x
x=83.848797250859

now we have:
85.4 is 83.848797250859% of 101.85
