Final Answer:
The three ratios that are equivalent to 16:12 are:
(choice b)

(choice c)

(choice e)

The correct answer is choice b,c and e.
Step-by-step explanation:
The given ratio is 16:12. To find equivalent ratios, we can multiply or divide both parts of the ratio by the same non-zero number. Let's check the given choices:
Choice a (8:6): When you divide both parts of 16:12 by 2, you get 8:6, so this is an equivalent ratio.
Choice b (32:24): When you multiply both parts of 16:12 by 2, you get 32:24, making it an equivalent ratio.
Choice c 4:3: If you divide both parts of 16:12 by 4, you get 4:3, which is another equivalent ratio.
Choice d (12:8): If you divide both parts of 16:12 by 2, you get 8:6, not 12:8, so this is not an equivalent ratio.
Choice e (24:16): When you multiply both parts of 16:12 by 3, you get (48:36), and if you further simplify it by dividing both parts by 2, you get 24:16, which is an equivalent ratio.
Therefore, choices b, c, and e are the correct answers, as they provide ratios equivalent to 16:12.
Thus, The correct answer is choice b,c and e.
