What is 8.68 percent of 31 - 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 31 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 31 is 100%, so we can write it down as 31=100%.
4. We know, that x is 8.68% of the output value, so we can write it down as x=8.68%.
5. Now we have two simple equations:
1) 31=100%
2) x=8.68%
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:
31/x=100%/8.68%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 8.68% of 31

31/x=100/8.68
(31/x)*x=(100/8.68)*x       - we multiply both sides of the equation by x
31=11.520737327189*x       - we divide both sides of the equation by (11.520737327189) to get x
31/11.520737327189=x
2.6908=x
x=2.6908

now we have:
8.68% of 31=2.6908
