31.5 is what percent of 32.5 - 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 32.5 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 32.5, so we can write it down as 100%=32.5.
4. We know, that x% equals 31.5 of the output value, so we can write it down as x%=31.5.
5. Now we have two simple equations:
1) 100%=32.5
2) x%=31.5
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%=32.5/31.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 31.5 is what percent of 32.5

100%/x%=32.5/31.5
(100/x)*x=(32.5/31.5)*x       - we multiply both sides of the equation by x
100=1.031746031746*x       - we divide both sides of the equation by (1.031746031746) to get x
100/1.031746031746=x
96.923076923077=x
x=96.923076923077

now we have:
31.5 is 96.923076923077% of 32.5
