What is 455 percent of 9 - 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 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 is 100%, so we can write it down as 9=100%.
4. We know, that x is 455% of the output value, so we can write it down as x=455%.
5. Now we have two simple equations:
1) 9=100%
2) x=455%
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/x=100%/455%
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 455% of 9

9/x=100/455
(9/x)*x=(100/455)*x       - we multiply both sides of the equation by x
9=0.21978021978022*x       - we divide both sides of the equation by (0.21978021978022) to get x
9/0.21978021978022=x
40.95=x
x=40.95

now we have:
455% of 9=40.95
