What is 7800000000 percent of 8000000 - 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 8000000 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 8000000 is 100%, so we can write it down as 8000000=100%.
4. We know, that x is 7800000000% of the output value, so we can write it down as x=7800000000%.
5. Now we have two simple equations:
1) 8000000=100%
2) x=7800000000%
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:
8000000/x=100%/7800000000%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 7800000000% of 8000000

8000000/x=100/7800000000
(8000000/x)*x=(100/7800000000)*x       - we multiply both sides of the equation by x
8000000=1.2820512820513E-8*x       - we divide both sides of the equation by (1.2820512820513E-8) to get x
8000000/1.2820512820513E-8=x
6.24E+14=x
x=6.24E+14

now we have:
7800000000% of 8000000=6.24E+14
