48.3 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 48.3 of the output value, so we can write it down as x%=48.3.
5. Now we have two simple equations:
1) 100%=55
2) x%=48.3
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%=55/48.3
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 48.3 is what percent of 55

100%/x%=55/48.3
(100/x)*x=(55/48.3)*x       - we multiply both sides of the equation by x
100=1.1387163561077*x       - we divide both sides of the equation by (1.1387163561077) to get x
100/1.1387163561077=x
87.818181818182=x
x=87.818181818182

now we have:
48.3 is 87.818181818182% of 55
