What is 42900000 percent of 7.5 - 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 7.5 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 7.5 is 100%, so we can write it down as 7.5=100%.
4. We know, that x is 42900000% of the output value, so we can write it down as x=42900000%.
5. Now we have two simple equations:
1) 7.5=100%
2) x=42900000%
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:
7.5/x=100%/42900000%
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 42900000% of 7.5

7.5/x=100/42900000
(7.5/x)*x=(100/42900000)*x       - we multiply both sides of the equation by x
7.5=2.3310023310023E-6*x       - we divide both sides of the equation by (2.3310023310023E-6) to get x
7.5/2.3310023310023E-6=x
3217500=x
x=3217500

now we have:
42900000% of 7.5=3217500
