Explanation:

- We need to find a number that is proportional to both 14 and 28.

- Two numbers are proportional if the ratio between them is the same.

- 14 and 28 have a ratio of 1:2 (since 28/14 = 2).

- Let’s compare each option to 14 and see if the ratio matches that of 28 and 14.

- Option 1: 65/14 ˜ 4.64 (not the same ratio as 28/14 = 2)

- Option 2: 16/14 ˜ 1.14 (again, not the same)

- Option 3: 24/14 ˜ 1.71 (not matching)

- Option 4: 56/28 = 2, and 28/14 = 2. So, 56 is proportional to 28 as 28 is to 14.

- Therefore, option 4 is the number that is proportional to 14 and 28.
