2.4 is what percent of 12.4 - 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 12.4 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 12.4, so we can write it down as 100%=12.4.
4. We know, that x% equals 2.4 of the output value, so we can write it down as x%=2.4.
5. Now we have two simple equations:
1) 100%=12.4
2) x%=2.4
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%=12.4/2.4
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 2.4 is what percent of 12.4

100%/x%=12.4/2.4
(100/x)*x=(12.4/2.4)*x       - we multiply both sides of the equation by x
100=5.1666666666667*x       - we divide both sides of the equation by (5.1666666666667) to get x
100/5.1666666666667=x
19.354838709677=x
x=19.354838709677

now we have:
2.4 is 19.354838709677% of 12.4
