What is 4.31 percent of 68.91 - 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 68.91 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 68.91 is 100%, so we can write it down as 68.91=100%.
4. We know, that x is 4.31% of the output value, so we can write it down as x=4.31%.
5. Now we have two simple equations:
1) 68.91=100%
2) x=4.31%
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:
68.91/x=100%/4.31%
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 4.31% of 68.91

68.91/x=100/4.31
(68.91/x)*x=(100/4.31)*x       - we multiply both sides of the equation by x
68.91=23.201856148492*x       - we divide both sides of the equation by (23.201856148492) to get x
68.91/23.201856148492=x
2.970021=x
x=2.970021

now we have:
4.31% of 68.91=2.970021
