Answer:
4 over 3 or 4 : 3.
Step-by-step explanation:
See the diagram attached.
Now, The ratio of X's to O's is 12 : 9.
Now, we have to determine another ration for X's to O's.
The image will help us to do that.
There are 12 numbers of X and that can be broken into 3 sets of X with 4 X in each set. Hence, 12 = 3 × 4
Again, there are 9 numbers of O and that can be broken into 3 sets of O with 3 O in each set. Hence, 9 = 3 × 3
Therefore, the ratio of X's to O's is 12 : 9 ≡ (3 × 4) : (3 × 3) ≡ 4 : 3
