9 is what percent of 2486 - 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 2486 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 2486, so we can write it down as 100%=2486.
4. We know, that x% equals 9 of the output value, so we can write it down as x%=9.
5. Now we have two simple equations:
1) 100%=2486
2) x%=9
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%=2486/9
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 9 is what percent of 2486

100%/x%=2486/9
(100/x)*x=(2486/9)*x       - we multiply both sides of the equation by x
100=276.22222222222*x       - we divide both sides of the equation by (276.22222222222) to get x
100/276.22222222222=x
0.3620273531778=x
x=0.3620273531778

now we have:
9 is 0.3620273531778% of 2486
