What is 72000 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 72000% of the output value, so we can write it down as x=72000%.
5. Now we have two simple equations:
1) 7.5=100%
2) x=72000%
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%/72000%
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 72000% of 7.5

7.5/x=100/72000
(7.5/x)*x=(100/72000)*x       - we multiply both sides of the equation by x
7.5=0.0013888888888889*x       - we divide both sides of the equation by (0.0013888888888889) to get x
7.5/0.0013888888888889=x
5400=x
x=5400

now we have:
72000% of 7.5=5400
