81.5 is what percent of 1036 - 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 1036 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 1036, so we can write it down as 100%=1036.
4. We know, that x% equals 81.5 of the output value, so we can write it down as x%=81.5.
5. Now we have two simple equations:
1) 100%=1036
2) x%=81.5
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%=1036/81.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 81.5 is what percent of 1036

100%/x%=1036/81.5
(100/x)*x=(1036/81.5)*x       - we multiply both sides of the equation by x
100=12.711656441718*x       - we divide both sides of the equation by (12.711656441718) to get x
100/12.711656441718=x
7.8667953667954=x
x=7.8667953667954

now we have:
81.5 is 7.8667953667954% of 1036
