Answer: 3:4 AND 12:16
Step-by-step explanation: To get a ratio both numbers need to be easily divided. 6 can be divided by 2 and get 3. 8 can be divided by 2 also and get 4. So yes that one would work. 16 divided by 8 is 2 and 12 divided by 6 is also 2. Since both numbers are the same, this ratio would also be equivalent. Hope this helps :)
