13.78 is what percent of 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 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 48, so we can write it down as 100%=48.
4. We know, that x% equals 13.78 of the output value, so we can write it down as x%=13.78.
5. Now we have two simple equations:
1) 100%=48
2) x%=13.78
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%=48/13.78
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 13.78 is what percent of 48

100%/x%=48/13.78
(100/x)*x=(48/13.78)*x       - we multiply both sides of the equation by x
100=3.4833091436865*x       - we divide both sides of the equation by (3.4833091436865) to get x
100/3.4833091436865=x
28.708333333333=x
x=28.708333333333

now we have:
13.78 is 28.708333333333% of 48
