5 is what percent of 39000000 - 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 39000000 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 39000000, so we can write it down as 100%=39000000.
4. We know, that x% equals 5 of the output value, so we can write it down as x%=5.
5. Now we have two simple equations:
1) 100%=39000000
2) x%=5
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%=39000000/5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 5 is what percent of 39000000

100%/x%=39000000/5
(100/x)*x=(39000000/5)*x       - we multiply both sides of the equation by x
100=7800000*x       - we divide both sides of the equation by (7800000) to get x
100/7800000=x
1.2820512820513E-5=x
x=1.2820512820513E-5

now we have:
5 is 1.2820512820513E-5% of 39000000
