Answer :

So, It may be 24/2 and 96/2. 24/3=12, and 96/2=48, so it might be 12:48. 
The comparison for the ratio of 24 and 96 is 24:96

But you can reduce the ratio. Divide both sides by 2

24÷2=12
96÷2=48

Now it is 12:48

Again, to simplify, you divide both sides by 2

12÷2=6
48÷2=24

Now it is 6:24

Again, to simplify, you divide both sides by 2

6÷2=3
24÷2=12

3:12

Now you divide both sides by 3

3÷3=1
12÷3=4

1:4 is your ratio simplified.
