39 is what percent of 66000000 - 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 66000000 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 66000000, so we can write it down as 100%=66000000.
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%=66000000
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%=66000000/39
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 66000000

100%/x%=66000000/39
(100/x)*x=(66000000/39)*x       - we multiply both sides of the equation by x
100=1692307.6923077*x       - we divide both sides of the equation by (1692307.6923077) to get x
100/1692307.6923077=x
5.9090909090909E-5=x
x=5.9090909090909E-5

now we have:
39 is 5.9090909090909E-5% of 66000000
