413.2 is what percent of 1686 - 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 1686 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 1686, so we can write it down as 100%=1686.
4. We know, that x% equals 413.2 of the output value, so we can write it down as x%=413.2.
5. Now we have two simple equations:
1) 100%=1686
2) x%=413.2
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%=1686/413.2
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 413.2 is what percent of 1686

100%/x%=1686/413.2
(100/x)*x=(1686/413.2)*x       - we multiply both sides of the equation by x
100=4.080348499516*x       - we divide both sides of the equation by (4.080348499516) to get x
100/4.080348499516=x
24.507710557533=x
x=24.507710557533

now we have:
413.2 is 24.507710557533% of 1686
