82.5 is what percent of 156 - 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 156 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 156, so we can write it down as 100%=156.
4. We know, that x% equals 82.5 of the output value, so we can write it down as x%=82.5.
5. Now we have two simple equations:
1) 100%=156
2) x%=82.5
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%=156/82.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 82.5 is what percent of 156

100%/x%=156/82.5
(100/x)*x=(156/82.5)*x       - we multiply both sides of the equation by x
100=1.8909090909091*x       - we divide both sides of the equation by (1.8909090909091) to get x
100/1.8909090909091=x
52.884615384615=x
x=52.884615384615

now we have:
82.5 is 52.884615384615% of 156
