3.93 is what percent of 7800000000 - 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 7800000000 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 7800000000, so we can write it down as 100%=7800000000.
4. We know, that x% equals 3.93 of the output value, so we can write it down as x%=3.93.
5. Now we have two simple equations:
1) 100%=7800000000
2) x%=3.93
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%=7800000000/3.93
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 3.93 is what percent of 7800000000

100%/x%=7800000000/3.93
(100/x)*x=(7800000000/3.93)*x       - we multiply both sides of the equation by x
100=1984732824.4275*x       - we divide both sides of the equation by (1984732824.4275) to get x
100/1984732824.4275=x
5.0384615384615E-8=x
x=5.0384615384615E-8

now we have:
3.93 is 5.0384615384615E-8% of 7800000000
