39 is what percent of 1413 - 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 1413 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 1413, so we can write it down as 100%=1413.
4. We know, that x% equals 39 of the output value, so we can write it down as x%=39.
5. Now we have two simple equations:
1) 100%=1413
2) x%=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%=1413/39
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 39 is what percent of 1413

100%/x%=1413/39
(100/x)*x=(1413/39)*x       - we multiply both sides of the equation by x
100=36.230769230769*x       - we divide both sides of the equation by (36.230769230769) to get x
100/36.230769230769=x
2.76008492569=x
x=2.76008492569

now we have:
39 is 2.76008492569% of 1413
