31 is what percent of 36.6 - 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 36.6 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 36.6, so we can write it down as 100%=36.6.
4. We know, that x% equals 31 of the output value, so we can write it down as x%=31.
5. Now we have two simple equations:
1) 100%=36.6
2) x%=31
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%=36.6/31
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 31 is what percent of 36.6

100%/x%=36.6/31
(100/x)*x=(36.6/31)*x       - we multiply both sides of the equation by x
100=1.1806451612903*x       - we divide both sides of the equation by (1.1806451612903) to get x
100/1.1806451612903=x
84.699453551913=x
x=84.699453551913

now we have:
31 is 84.699453551913% of 36.6
