What is 31.1688 percent of 7 - 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 7 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 7 is 100%, so we can write it down as 7=100%.
4. We know, that x is 31.1688% of the output value, so we can write it down as x=31.1688%.
5. Now we have two simple equations:
1) 7=100%
2) x=31.1688%
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:
7/x=100%/31.1688%
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 31.1688% of 7

7/x=100/31.1688
(7/x)*x=(100/31.1688)*x       - we multiply both sides of the equation by x
7=3.2083365416699*x       - we divide both sides of the equation by (3.2083365416699) to get x
7/3.2083365416699=x
2.181816=x
x=2.181816

now we have:
31.1688% of 7=2.181816
