19.2 is what percent of 168 - 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 168 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 168, so we can write it down as 100%=168.
4. We know, that x% equals 19.2 of the output value, so we can write it down as x%=19.2.
5. Now we have two simple equations:
1) 100%=168
2) x%=19.2
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%=168/19.2
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 19.2 is what percent of 168

100%/x%=168/19.2
(100/x)*x=(168/19.2)*x       - we multiply both sides of the equation by x
100=8.75*x       - we divide both sides of the equation by (8.75) to get x
100/8.75=x
11.428571428571=x
x=11.428571428571

now we have:
19.2 is 11.428571428571% of 168
