What is 5200 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 5200% of the output value, so we can write it down as x=5200%.
5. Now we have two simple equations:
1) 7.5=100%
2) x=5200%
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%/5200%
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 5200% of 7.5

7.5/x=100/5200
(7.5/x)*x=(100/5200)*x       - we multiply both sides of the equation by x
7.5=0.019230769230769*x       - we divide both sides of the equation by (0.019230769230769) to get x
7.5/0.019230769230769=x
390=x
x=390

now we have:
5200% of 7.5=390
