Answer is 3:4
==========================================================
Reason:
There are 9 goals in 12 games, which produces the ratio 9:12. The order of the values is important since we list the goals first (because we have "goals" before "games" mentioned).
After setting up 9:12, we divide both parts by the GCF 3
9/3 = 3
12/3 = 4
The ratio 9:12 fully reduces to 3:4 as the final answer
