📝 Explanation:

- Each problem involves multiplying a two-digit number by a single-digit number.
- We used the distributive property:
For example:
$ 92 \times 7 = (90 + 2) \times 7 = 90\times7 + 2\times7 $
- This method breaks down the problem into simpler parts.
- Multiplication facts for single digits are essential here.
- Practice helps build speed and accuracy.
