9 is what percent of 47000000 - 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 47000000 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 47000000, so we can write it down as 100%=47000000.
4. We know, that x% equals 9 of the output value, so we can write it down as x%=9.
5. Now we have two simple equations:
1) 100%=47000000
2) x%=9
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%=47000000/9
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 9 is what percent of 47000000

100%/x%=47000000/9
(100/x)*x=(47000000/9)*x       - we multiply both sides of the equation by x
100=5222222.2222222*x       - we divide both sides of the equation by (5222222.2222222) to get x
100/5222222.2222222=x
1.9148936170213E-5=x
x=1.9148936170213E-5

now we have:
9 is 1.9148936170213E-5% of 47000000
