What is 250000000 percent of 75 - 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 75 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 75 is 100%, so we can write it down as 75=100%.
4. We know, that x is 250000000% of the output value, so we can write it down as x=250000000%.
5. Now we have two simple equations:
1) 75=100%
2) x=250000000%
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:
75/x=100%/250000000%
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 250000000% of 75

75/x=100/250000000
(75/x)*x=(100/250000000)*x       - we multiply both sides of the equation by x
75=4.0E-7*x       - we divide both sides of the equation by (4.0E-7) to get x
75/4.0E-7=x
187500000=x
x=187500000

now we have:
250000000% of 75=187500000
