What is 45000000 percent of 78000000000 - 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 78000000000 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 78000000000 is 100%, so we can write it down as 78000000000=100%.
4. We know, that x is 45000000% of the output value, so we can write it down as x=45000000%.
5. Now we have two simple equations:
1) 78000000000=100%
2) x=45000000%
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:
78000000000/x=100%/45000000%
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 45000000% of 78000000000

78000000000/x=100/45000000
(78000000000/x)*x=(100/45000000)*x       - we multiply both sides of the equation by x
78000000000=2.2222222222222E-6*x       - we divide both sides of the equation by (2.2222222222222E-6) to get x
78000000000/2.2222222222222E-6=x
3.51E+16=x
x=3.51E+16

now we have:
45000000% of 78000000000=3.51E+16
