2. Yes
3. No
4. Yes
5. Yes

Step-by-step explanation:

If you want to have a checking, multiply the pair of numbers, the means and extremes like 1.

• Extreme:Mean=Mean: Extreme
• 3:4=12:16
• Means are 4 and 12
• Extremes are 3 and 16
• Multiply the pair of numbers. If they got the same product,then the ratios showed proportion.
• So 4 × 12 is 48 while 3 × 16 is 48 also.
• This means that the ratios 3:4=12:16 showed proportion.
