212.12 is what percent of 82.5 - 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 82.5 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 82.5, so we can write it down as 100%=82.5.
4. We know, that x% equals 212.12 of the output value, so we can write it down as x%=212.12.
5. Now we have two simple equations:
1) 100%=82.5
2) x%=212.12
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%=82.5/212.12
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 212.12 is what percent of 82.5

100%/x%=82.5/212.12
(100/x)*x=(82.5/212.12)*x       - we multiply both sides of the equation by x
100=0.38893079389025*x       - we divide both sides of the equation by (0.38893079389025) to get x
100/0.38893079389025=x
257.11515151515=x
x=257.11515151515

now we have:
212.12 is 257.11515151515% of 82.5
