What is 5000000 percent of 780000000000 - 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 780000000000 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 780000000000 is 100%, so we can write it down as 780000000000=100%.
4. We know, that x is 5000000% of the output value, so we can write it down as x=5000000%.
5. Now we have two simple equations:
1) 780000000000=100%
2) x=5000000%
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:
780000000000/x=100%/5000000%
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 5000000% of 780000000000

780000000000/x=100/5000000
(780000000000/x)*x=(100/5000000)*x       - we multiply both sides of the equation by x
780000000000=2.0E-5*x       - we divide both sides of the equation by (2.0E-5) to get x
780000000000/2.0E-5=x
3.9E+16=x
x=3.9E+16

now we have:
5000000% of 780000000000=3.9E+16
