16.5 is what percent of 512 - 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 512 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 512, so we can write it down as 100%=512.
4. We know, that x% equals 16.5 of the output value, so we can write it down as x%=16.5.
5. Now we have two simple equations:
1) 100%=512
2) x%=16.5
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%=512/16.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 16.5 is what percent of 512

100%/x%=512/16.5
(100/x)*x=(512/16.5)*x       - we multiply both sides of the equation by x
100=31.030303030303*x       - we divide both sides of the equation by (31.030303030303) to get x
100/31.030303030303=x
3.22265625=x
x=3.22265625

now we have:
16.5 is 3.22265625% of 512
