66 is what percent of 3000000000 - 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 3000000000 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 3000000000, so we can write it down as 100%=3000000000.
4. We know, that x% equals 66 of the output value, so we can write it down as x%=66.
5. Now we have two simple equations:
1) 100%=3000000000
2) x%=66
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%=3000000000/66
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 66 is what percent of 3000000000

100%/x%=3000000000/66
(100/x)*x=(3000000000/66)*x       - we multiply both sides of the equation by x
100=45454545.454545*x       - we divide both sides of the equation by (45454545.454545) to get x
100/45454545.454545=x
2.2E-6=x
x=2.2E-6

now we have:
66 is 2.2E-6% of 3000000000
