16.8 is what percent of 12.3 - 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 12.3 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 12.3, so we can write it down as 100%=12.3.
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%=12.3
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%=12.3/16.8
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 12.3

100%/x%=12.3/16.8
(100/x)*x=(12.3/16.8)*x       - we multiply both sides of the equation by x
100=0.73214285714286*x       - we divide both sides of the equation by (0.73214285714286) to get x
100/0.73214285714286=x
136.58536585366=x
x=136.58536585366

now we have:
16.8 is 136.58536585366% of 12.3
