Step-by-step explanation:

Answer 2

The pairs of ratios that form a proportion are:

A:3/11 and 15/33

B: 42/18 and 7/3

Step-by-step explanation:

A proportion exists when two ratios are equivalent. We can check this by cross-multiplication:

3/11 * 33 = 15/33 * 11 (True)

42/18 * 3 = 7/3 * 42 (True)

Therefore, the first and second pairs fulfill the condition of a proportion, while the remaining pairs do not.

Options A and B are answers.
