23 is what percent of 107.5 - 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 107.5 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 100% equals 107.5, so we can write it down as 100%=107.5.
4. We know, that x% equals 23 of the output value, so we can write it down as x%=23.
5. Now we have two simple equations:
1) 100%=107.5
2) x%=23
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:
100%/x%=107.5/23
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 23 is what percent of 107.5

100%/x%=107.5/23
(100/x)*x=(107.5/23)*x       - we multiply both sides of the equation by x
100=4.6739130434783*x       - we divide both sides of the equation by (4.6739130434783) to get x
100/4.6739130434783=x
21.395348837209=x
x=21.395348837209

now we have:
23 is 21.395348837209% of 107.5
