63.5 is what percent of 82 - 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 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, so we can write it down as 100%=82.
4. We know, that x% equals 63.5 of the output value, so we can write it down as x%=63.5.
5. Now we have two simple equations:
1) 100%=82
2) x%=63.5
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%=82/63.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 63.5 is what percent of 82

100%/x%=82/63.5
(100/x)*x=(82/63.5)*x       - we multiply both sides of the equation by x
100=1.2913385826772*x       - we divide both sides of the equation by (1.2913385826772) to get x
100/1.2913385826772=x
77.439024390244=x
x=77.439024390244

now we have:
63.5 is 77.439024390244% of 82
