26.5 is what percent of 87 - 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 87 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 87, so we can write it down as 100%=87.
4. We know, that x% equals 26.5 of the output value, so we can write it down as x%=26.5.
5. Now we have two simple equations:
1) 100%=87
2) x%=26.5
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%=87/26.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 26.5 is what percent of 87

100%/x%=87/26.5
(100/x)*x=(87/26.5)*x       - we multiply both sides of the equation by x
100=3.2830188679245*x       - we divide both sides of the equation by (3.2830188679245) to get x
100/3.2830188679245=x
30.459770114943=x
x=30.459770114943

now we have:
26.5 is 30.459770114943% of 87
