47.2 is what percent of 12.5 - 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 12.5 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 12.5, so we can write it down as 100%=12.5.
4. We know, that x% equals 47.2 of the output value, so we can write it down as x%=47.2.
5. Now we have two simple equations:
1) 100%=12.5
2) x%=47.2
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%=12.5/47.2
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 47.2 is what percent of 12.5

100%/x%=12.5/47.2
(100/x)*x=(12.5/47.2)*x       - we multiply both sides of the equation by x
100=0.26483050847458*x       - we divide both sides of the equation by (0.26483050847458) to get x
100/0.26483050847458=x
377.6=x
x=377.6

now we have:
47.2 is 377.6% of 12.5
