411.25 is what percent of 520 - 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 520 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 520, so we can write it down as 100%=520.
4. We know, that x% equals 411.25 of the output value, so we can write it down as x%=411.25.
5. Now we have two simple equations:
1) 100%=520
2) x%=411.25
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%=520/411.25
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 411.25 is what percent of 520

100%/x%=520/411.25
(100/x)*x=(520/411.25)*x       - we multiply both sides of the equation by x
100=1.2644376899696*x       - we divide both sides of the equation by (1.2644376899696) to get x
100/1.2644376899696=x
79.086538461538=x
x=79.086538461538

now we have:
411.25 is 79.086538461538% of 520
