18.39 is what percent of 75.38 - 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 75.38 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 75.38, so we can write it down as 100%=75.38.
4. We know, that x% equals 18.39 of the output value, so we can write it down as x%=18.39.
5. Now we have two simple equations:
1) 100%=75.38
2) x%=18.39
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%=75.38/18.39
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 18.39 is what percent of 75.38

100%/x%=75.38/18.39
(100/x)*x=(75.38/18.39)*x       - we multiply both sides of the equation by x
100=4.0989668297988*x       - we divide both sides of the equation by (4.0989668297988) to get x
100/4.0989668297988=x
24.396391615813=x
x=24.396391615813

now we have:
18.39 is 24.396391615813% of 75.38
