42.85 is what percent of 52.207 - 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 52.207 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 52.207, so we can write it down as 100%=52.207.
4. We know, that x% equals 42.85 of the output value, so we can write it down as x%=42.85.
5. Now we have two simple equations:
1) 100%=52.207
2) x%=42.85
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%=52.207/42.85
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 42.85 is what percent of 52.207

100%/x%=52.207/42.85
(100/x)*x=(52.207/42.85)*x       - we multiply both sides of the equation by x
100=1.2183663943991*x       - we divide both sides of the equation by (1.2183663943991) to get x
100/1.2183663943991=x
82.077116095543=x
x=82.077116095543

now we have:
