12.96 is what percent of 27 - 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 27 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 27, so we can write it down as 100%=27.
4. We know, that x% equals 12.96 of the output value, so we can write it down as x%=12.96.
5. Now we have two simple equations:
1) 100%=27
2) x%=12.96
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%=27/12.96
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 12.96 is what percent of 27

100%/x%=27/12.96
(100/x)*x=(27/12.96)*x       - we multiply both sides of the equation by x
100=2.0833333333333*x       - we divide both sides of the equation by (2.0833333333333) to get x
100/2.0833333333333=x
48=x
x=48

now we have:
12.96 is 48% of 27
