411.5 is what percent of 1002.5 - 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 1002.5 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 100% equals 1002.5, so we can write it down as 100%=1002.5.
4. We know, that x% equals 411.5 of the output value, so we can write it down as x%=411.5.
5. Now we have two simple equations:
1) 100%=1002.5
2) x%=411.5
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%=1002.5/411.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 411.5 is what percent of 1002.5

100%/x%=1002.5/411.5
(100/x)*x=(1002.5/411.5)*x       - we multiply both sides of the equation by x
100=2.4362089914945*x       - we divide both sides of the equation by (2.4362089914945) to get x
100/2.4362089914945=x
41.047381546135=x
x=41.047381546135

now we have:
411.5 is 41.047381546135% of 1002.5
