102.5 is what percent of 156.5 - 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 156.5 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 156.5, so we can write it down as 100%=156.5.
4. We know, that x% equals 102.5 of the output value, so we can write it down as x%=102.5.
5. Now we have two simple equations:
1) 100%=156.5
2) x%=102.5
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%=156.5/102.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 102.5 is what percent of 156.5

100%/x%=156.5/102.5
(100/x)*x=(156.5/102.5)*x       - we multiply both sides of the equation by x
100=1.5268292682927*x       - we divide both sides of the equation by (1.5268292682927) to get x
100/1.5268292682927=x
65.495207667732=x
x=65.495207667732

now we have:
102.5 is 65.495207667732% of 156.5
