3.96 is what percent of 55 - 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 55 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 55, so we can write it down as 100%=55.
4. We know, that x% equals 3.96 of the output value, so we can write it down as x%=3.96.
5. Now we have two simple equations:
1) 100%=55
2) x%=3.96
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%=55/3.96
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 3.96 is what percent of 55

100%/x%=55/3.96
(100/x)*x=(55/3.96)*x       - we multiply both sides of the equation by x
100=13.888888888889*x       - we divide both sides of the equation by (13.888888888889) to get x
100/13.888888888889=x
7.2=x
x=7.2

now we have:
3.96 is 7.2% of 55
