What is 400.09 percent of 9.75 - 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 9.75 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 9.75 is 100%, so we can write it down as 9.75=100%.
4. We know, that x is 400.09% of the output value, so we can write it down as x=400.09%.
5. Now we have two simple equations:
1) 9.75=100%
2) x=400.09%
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:
9.75/x=100%/400.09%
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 400.09% of 9.75

9.75/x=100/400.09
(9.75/x)*x=(100/400.09)*x       - we multiply both sides of the equation by x
9.75=0.2499437626534*x       - we divide both sides of the equation by (0.2499437626534) to get x
9.75/0.2499437626534=x
39.008775=x
x=39.008775

now we have:
400.09% of 9.75=39.008775
