12.48 is what percent of 30 - 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 30 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 30, so we can write it down as 100%=30.
4. We know, that x% equals 12.48 of the output value, so we can write it down as x%=12.48.
5. Now we have two simple equations:
1) 100%=30
2) x%=12.48
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%=30/12.48
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 12.48 is what percent of 30

100%/x%=30/12.48
(100/x)*x=(30/12.48)*x       - we multiply both sides of the equation by x
100=2.4038461538462*x       - we divide both sides of the equation by (2.4038461538462) to get x
100/2.4038461538462=x
41.6=x
x=41.6

now we have:
12.48 is 41.6% of 30
