Answer:
2:10, and 3:15
Explanation:
One of the answers is 2:10 as you do whatever you do to the right you have to do to the left and so you do 2 times 3 as that's what you have to do to get to 2. You do the same to the 5 (basically times 2 and you will get 10). So the ratio you get in the end will be 2:10.
Another one of the answers is 3:15 and as I said before whatever you do to the right you have to do the left and so you do 1 tine 3 which gets you to 3. You do the same to the left and you will get 15. So the ratio in the end will be 3:15.
