35.81 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 35.81 of the output value, so we can write it down as x%=35.81.
5. Now we have two simple equations:
1) 100%=87
2) x%=35.81
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%=87/35.81
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 35.81 is what percent of 87

100%/x%=87/35.81
(100/x)*x=(87/35.81)*x       - we multiply both sides of the equation by x
100=2.4294889695616*x       - we divide both sides of the equation by (2.4294889695616) to get x
100/2.4294889695616=x
41.16091954023=x
x=41.16091954023

now we have:
35.81 is 41.16091954023% of 87
