🔍 Explanation:

Each problem is a two-digit number multiplied by a one-digit number. The strategy used here is distributive property:
$$
(a + b) \times c = a \times c + b \times c
$$

For example:
- $ 47 \times 9 = (40 + 7) \times 9 = 40 \times 9 + 7 \times 9 = 360 + 63 = 423 $

This method helps break down larger multiplications into simpler parts.

You can verify any answer using a calculator or by standard multiplication.
