24 is what percent of 27.9 - 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 27.9 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 27.9, so we can write it down as 100%=27.9.
4. We know, that x% equals 24 of the output value, so we can write it down as x%=24.
5. Now we have two simple equations:
1) 100%=27.9
2) x%=24
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%=27.9/24
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 24 is what percent of 27.9

100%/x%=27.9/24
(100/x)*x=(27.9/24)*x       - we multiply both sides of the equation by x
100=1.1625*x       - we divide both sides of the equation by (1.1625) to get x
100/1.1625=x
86.021505376344=x
x=86.021505376344

now we have:
24 is 86.021505376344% of 27.9
