23.68 is what percent of 21 - 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 21 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 21, so we can write it down as 100%=21.
4. We know, that x% equals 23.68 of the output value, so we can write it down as x%=23.68.
5. Now we have two simple equations:
1) 100%=21
2) x%=23.68
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%=21/23.68
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 23.68 is what percent of 21

100%/x%=21/23.68
(100/x)*x=(21/23.68)*x       - we multiply both sides of the equation by x
100=0.88682432432432*x       - we divide both sides of the equation by (0.88682432432432) to get x
100/0.88682432432432=x
112.7619047619=x
x=112.7619047619

now we have:
23.68 is 112.7619047619% of 21
