What is 39.4 percent of 22.8 - 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 22.8 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 22.8 is 100%, so we can write it down as 22.8=100%.
4. We know, that x is 39.4% of the output value, so we can write it down as x=39.4%.
5. Now we have two simple equations:
1) 22.8=100%
2) x=39.4%
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:
22.8/x=100%/39.4%
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 39.4% of 22.8

22.8/x=100/39.4
(22.8/x)*x=(100/39.4)*x       - we multiply both sides of the equation by x
22.8=2.5380710659898*x       - we divide both sides of the equation by (2.5380710659898) to get x
22.8/2.5380710659898=x
8.9832=x
x=8.9832

now we have:
39.4% of 22.8=8.9832
