682.5 is what percent of 4480 - 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 4480 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 100% equals 4480, so we can write it down as 100%=4480.
4. We know, that x% equals 682.5 of the output value, so we can write it down as x%=682.5.
5. Now we have two simple equations:
1) 100%=4480
2) x%=682.5
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:
100%/x%=4480/682.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 682.5 is what percent of 4480

100%/x%=4480/682.5
(100/x)*x=(4480/682.5)*x       - we multiply both sides of the equation by x
100=6.5641025641026*x       - we divide both sides of the equation by (6.5641025641026) to get x
100/6.5641025641026=x
15.234375=x
x=15.234375

now we have:
682.5 is 15.234375% of 4480
