What is 50000000 percent of 7.5E+15 - 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 7.5E+15 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 7.5E+15 is 100%, so we can write it down as 7.5E+15=100%.
4. We know, that x is 50000000% of the output value, so we can write it down as x=50000000%.
5. Now we have two simple equations:
1) 7.5E+15=100%
2) x=50000000%
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:
7.5E+15/x=100%/50000000%
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 50000000% of 7.5E+15

7.5E+15/x=100/50000000
(7.5E+15/x)*x=(100/50000000)*x       - we multiply both sides of the equation by x
7.5E+15=2.0E-6*x       - we divide both sides of the equation by (2.0E-6) to get x
7.5E+15/2.0E-6=x
3.75E+21=x
x=3.75E+21

now we have:
50000000% of 7.5E+15=3.75E+21
