<u>Given</u>:
The given ratio is 
We need to determine three ratios that are equivalent to the given ratio.
<u>Option A</u>: 
The given ratio is 
Let us divide the given ratio 
 by 2.
Thus, we have;

Hence, the expression 
 is equivalent to 
Thus, Option A is the correct answer.
<u>Option B</u>: 
The number 32 goes by 16 in 2 times and the number 24 goes by 12 in 2 times.
Thus, multiplying the ratio 
 by 2, we get;

Thus, the expression 
 is equivalent to 
Hence, Option B is the correct answer.
<u>Option C</u>: 
Let us divide the given ratio 
 by 4.
Thus, we have;

Thus, the expression 
 is equivalent to 
Hence, Option C is the correct answer.
<u>Option D</u>: 
The number 12 goes by 16 in 
 times and the number 8 goes by 12 in 
 times.
The ratios are multiplied by different numbers.
Thus, the expression 
 is not equivalent to 
Hence, Option D is not the correct answer.
<u>Option E</u>: 
The number 24 goes by 16 in 1.5 times and the number 16 goes by 12 in 0.75 times.
The ratios are multiplied by different numbers.
Thus, the expression 
 is not equivalent to 
Hence, Option E is not the correct answer.
Therefore, the equivalent ratios are Option A, B and C
