16.8 is what percent of 53.5 - 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 53.5 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 53.5, so we can write it down as 100%=53.5.
4. We know, that x% equals 16.8 of the output value, so we can write it down as x%=16.8.
5. Now we have two simple equations:
1) 100%=53.5
2) x%=16.8
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%=53.5/16.8
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 16.8 is what percent of 53.5

100%/x%=53.5/16.8
(100/x)*x=(53.5/16.8)*x       - we multiply both sides of the equation by x
100=3.1845238095238*x       - we divide both sides of the equation by (3.1845238095238) to get x
100/3.1845238095238=x
31.401869158879=x
x=31.401869158879

now we have:
16.8 is 31.401869158879% of 53.5
