39 is what percent of 855000 - 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 855000 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 855000, so we can write it down as 100%=855000.
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%=855000
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%=855000/39
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 855000

100%/x%=855000/39
(100/x)*x=(855000/39)*x       - we multiply both sides of the equation by x
100=21923.076923077*x       - we divide both sides of the equation by (21923.076923077) to get x
100/21923.076923077=x
0.0045614035087719=x
x=0.0045614035087719

now we have:
39 is 0.0045614035087719% of 855000
