21.65 is what percent of 24 - 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 24 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 24, so we can write it down as 100%=24.
4. We know, that x% equals 21.65 of the output value, so we can write it down as x%=21.65.
5. Now we have two simple equations:
1) 100%=24
2) x%=21.65
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%=24/21.65
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 21.65 is what percent of 24

100%/x%=24/21.65
(100/x)*x=(24/21.65)*x       - we multiply both sides of the equation by x
100=1.108545034642*x       - we divide both sides of the equation by (1.108545034642) to get x
100/1.108545034642=x
90.208333333333=x
x=90.208333333333

now we have:
21.65 is 90.208333333333% of 24
