What is 7.725 percent of 31.29 - 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 31.29 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 31.29 is 100%, so we can write it down as 31.29=100%.
4. We know, that x is 7.725% of the output value, so we can write it down as x=7.725%.
5. Now we have two simple equations:
1) 31.29=100%
2) x=7.725%
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:
31.29/x=100%/7.725%
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 7.725% of 31.29

31.29/x=100/7.725
(31.29/x)*x=(100/7.725)*x       - we multiply both sides of the equation by x
31.29=12.94498381877*x       - we divide both sides of the equation by (12.94498381877) to get x
31.29/12.94498381877=x
2.4171525=x
x=2.4171525

now we have:
7.725% of 31.29=2.4171525
