15.38 is what percent of 54.88 - 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 54.88 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 54.88, so we can write it down as 100%=54.88.
4. We know, that x% equals 15.38 of the output value, so we can write it down as x%=15.38.
5. Now we have two simple equations:
1) 100%=54.88
2) x%=15.38
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%=54.88/15.38
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 15.38 is what percent of 54.88

100%/x%=54.88/15.38
(100/x)*x=(54.88/15.38)*x       - we multiply both sides of the equation by x
100=3.5682704811443*x       - we divide both sides of the equation by (3.5682704811443) to get x
100/3.5682704811443=x
28.024781341108=x
x=28.024781341108

now we have:
15.38 is 28.024781341108% of 54.88
