16.8 is what percent of 4.8 - 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 4.8 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 4.8, so we can write it down as 100%=4.8.
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%=4.8
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%=4.8/16.8
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 4.8

100%/x%=4.8/16.8
(100/x)*x=(4.8/16.8)*x       - we multiply both sides of the equation by x
100=0.28571428571429*x       - we divide both sides of the equation by (0.28571428571429) to get x
100/0.28571428571429=x
350=x
x=350

now we have:
16.8 is 350% of 4.8
