85 is what percent of 152.1 - 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 152.1 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 152.1, so we can write it down as 100%=152.1.
4. We know, that x% equals 85 of the output value, so we can write it down as x%=85.
5. Now we have two simple equations:
1) 100%=152.1
2) x%=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%=152.1/85
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 85 is what percent of 152.1

100%/x%=152.1/85
(100/x)*x=(152.1/85)*x       - we multiply both sides of the equation by x
100=1.7894117647059*x       - we divide both sides of the equation by (1.7894117647059) to get x
100/1.7894117647059=x
55.884286653517=x
x=55.884286653517

now we have:
85 is 55.884286653517% of 152.1
