5.39 is what percent of 12 - 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 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, so we can write it down as 100%=12.
4. We know, that x% equals 5.39 of the output value, so we can write it down as x%=5.39.
5. Now we have two simple equations:
1) 100%=12
2) x%=5.39
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%=12/5.39
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 5.39 is what percent of 12

100%/x%=12/5.39
(100/x)*x=(12/5.39)*x       - we multiply both sides of the equation by x
100=2.2263450834879*x       - we divide both sides of the equation by (2.2263450834879) to get x
100/2.2263450834879=x
44.916666666667=x
x=44.916666666667

now we have:
5.39 is 44.916666666667% of 12
