2. The second pair is 726191 and 726191 – these numbers are exactly the same, meaning they are **alike**.

3. The third pair is 827015 and 820715 – these numbers differ in the second digit (2 vs. 0), so they are **not alike**.

4. The fourth pair is 287651 and 287651 – these numbers are identical, thus they are **alike**.

5. The fifth pair is 009824 and 008924 – these numbers differ by the second digit (9 vs. 8), making them **not alike**.

6. The sixth pair is 721182 and 721182 – these numbers are exactly the same and thus are **alike**.
