28.8 is what percent of 53.8 - 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 53.8 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 53.8, so we can write it down as 100%=53.8.
4. We know, that x% equals 28.8 of the output value, so we can write it down as x%=28.8.
5. Now we have two simple equations:
1) 100%=53.8
2) x%=28.8
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%=53.8/28.8
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 28.8 is what percent of 53.8

100%/x%=53.8/28.8
(100/x)*x=(53.8/28.8)*x       - we multiply both sides of the equation by x
100=1.8680555555556*x       - we divide both sides of the equation by (1.8680555555556) to get x
100/1.8680555555556=x
53.531598513011=x
x=53.531598513011

now we have:
28.8 is 53.531598513011% of 53.8
