11 is what percent of 285 - 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 285 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 285, so we can write it down as 100%=285.
4. We know, that x% equals 11 of the output value, so we can write it down as x%=11.
5. Now we have two simple equations:
1) 100%=285
2) x%=11
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%=285/11
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 11 is what percent of 285

100%/x%=285/11
(100/x)*x=(285/11)*x       - we multiply both sides of the equation by x
100=25.909090909091*x       - we divide both sides of the equation by (25.909090909091) to get x
100/25.909090909091=x
3.859649122807=x
x=3.859649122807

now we have:
11 is 3.859649122807% of 285
