28.6 is what percent of 66 - 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 66 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 66, so we can write it down as 100%=66.
4. We know, that x% equals 28.6 of the output value, so we can write it down as x%=28.6.
5. Now we have two simple equations:
1) 100%=66
2) x%=28.6
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%=66/28.6
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 28.6 is what percent of 66

100%/x%=66/28.6
(100/x)*x=(66/28.6)*x       - we multiply both sides of the equation by x
100=2.3076923076923*x       - we divide both sides of the equation by (2.3076923076923) to get x
100/2.3076923076923=x
43.333333333333=x
x=43.333333333333

now we have:
28.6 is 43.333333333333% of 66
