3.89 is what percent of 15.48 - 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 15.48 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 15.48, so we can write it down as 100%=15.48.
4. We know, that x% equals 3.89 of the output value, so we can write it down as x%=3.89.
5. Now we have two simple equations:
1) 100%=15.48
2) x%=3.89
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%=15.48/3.89
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 3.89 is what percent of 15.48

100%/x%=15.48/3.89
(100/x)*x=(15.48/3.89)*x       - we multiply both sides of the equation by x
100=3.9794344473008*x       - we divide both sides of the equation by (3.9794344473008) to get x
100/3.9794344473008=x
25.129198966408=x
x=25.129198966408

now we have:
3.89 is 25.129198966408% of 15.48
