78 is what percent of 12000000000 - 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 12000000000 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 12000000000, so we can write it down as 100%=12000000000.
4. We know, that x% equals 78 of the output value, so we can write it down as x%=78.
5. Now we have two simple equations:
1) 100%=12000000000
2) x%=78
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%=12000000000/78
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 78 is what percent of 12000000000

100%/x%=12000000000/78
(100/x)*x=(12000000000/78)*x       - we multiply both sides of the equation by x
100=153846153.84615*x       - we divide both sides of the equation by (153846153.84615) to get x
100/153846153.84615=x
6.5E-7=x
x=6.5E-7

now we have:
78 is 6.5E-7% of 12000000000
