19.21 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 19.21 of the output value, so we can write it down as x%=19.21.
5. Now we have two simple equations:
1) 100%=24
2) x%=19.21
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%=24/19.21
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 19.21 is what percent of 24

100%/x%=24/19.21
(100/x)*x=(24/19.21)*x       - we multiply both sides of the equation by x
100=1.249349297241*x       - we divide both sides of the equation by (1.249349297241) to get x
100/1.249349297241=x
80.041666666667=x
x=80.041666666667

now we have:
19.21 is 80.041666666667% of 24
