24.57 is what percent of 28 - 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 28 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 28, so we can write it down as 100%=28.
4. We know, that x% equals 24.57 of the output value, so we can write it down as x%=24.57.
5. Now we have two simple equations:
1) 100%=28
2) x%=24.57
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%=28/24.57
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 24.57 is what percent of 28

100%/x%=28/24.57
(100/x)*x=(28/24.57)*x       - we multiply both sides of the equation by x
100=1.1396011396011*x       - we divide both sides of the equation by (1.1396011396011) to get x
100/1.1396011396011=x
87.75=x
x=87.75

now we have:
24.57 is 87.75% of 28
