12.4 is what percent of 5.2 - 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 5.2 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 5.2, so we can write it down as 100%=5.2.
4. We know, that x% equals 12.4 of the output value, so we can write it down as x%=12.4.
5. Now we have two simple equations:
1) 100%=5.2
2) x%=12.4
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%=5.2/12.4
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 12.4 is what percent of 5.2

100%/x%=5.2/12.4
(100/x)*x=(5.2/12.4)*x       - we multiply both sides of the equation by x
100=0.41935483870968*x       - we divide both sides of the equation by (0.41935483870968) to get x
100/0.41935483870968=x
238.46153846154=x
x=238.46153846154

now we have:
12.4 is 238.46153846154% of 5.2
