0.85 is what percent of 102 - 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 102 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 102, so we can write it down as 100%=102.
4. We know, that x% equals 0.85 of the output value, so we can write it down as x%=0.85.
5. Now we have two simple equations:
1) 100%=102
2) x%=0.85
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%=102/0.85
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 0.85 is what percent of 102

100%/x%=102/0.85
(100/x)*x=(102/0.85)*x       - we multiply both sides of the equation by x
100=120*x       - we divide both sides of the equation by (120) to get x
100/120=x
0.83333333333333=x
x=0.83333333333333

now we have:
0.85 is 0.83333333333333% of 102
