What is 79.31 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 79.31% of the output value, so we can write it down as x=79.31%.
5. Now we have two simple equations:
1) 31=100%
2) x=79.31%
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:
31/x=100%/79.31%
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 79.31% of 31

31/x=100/79.31
(31/x)*x=(100/79.31)*x       - we multiply both sides of the equation by x
31=1.2608750472828*x       - we divide both sides of the equation by (1.2608750472828) to get x
31/1.2608750472828=x
24.5861=x
x=24.5861

now we have:
79.31% of 31=24.5861
