1. Doubling:

\[6 \times 8 = 3 \times (2 \times 8) = 3 \times 16 = 48\]

2. Halving:

\[1.5 \times 8 = \frac{3}{2} \times 8 = 3 \times (0.5 \times 8) = 3 \times 4 = 12\]

3. One more:

\[4 \times 8 = 3 \times 8 + 1 \times 8 = 24 + 8 = 32\]

4. One less:

\[2 \times 8 = 3 \times 8 - 1 \times 8 = 24 - 8 = 16\]

5. Multiplication by 10:

\[30 \times 8 = (3 \times 10) \times 8 = 3 \times (10 \times 8) = 3 \times 80 = 240\]

6. Multiplication by 100:

\[300 \times 8 = (3 \times 100) \times 8 = 3 \times (100 \times 8) = 3 \times 800 = 2400\]

These are just some examples of how the fact \(3 \times 8 = 24\) can be used to generate related multiplication problems.
