20.64 is what percent of 48 - 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 48 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 48, so we can write it down as 100%=48.
4. We know, that x% equals 20.64 of the output value, so we can write it down as x%=20.64.
5. Now we have two simple equations:
1) 100%=48
2) x%=20.64
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%=48/20.64
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 20.64 is what percent of 48

100%/x%=48/20.64
(100/x)*x=(48/20.64)*x       - we multiply both sides of the equation by x
100=2.3255813953488*x       - we divide both sides of the equation by (2.3255813953488) to get x
100/2.3255813953488=x
43=x
x=43

now we have:
20.64 is 43% of 48
