Find the value of [tex] ? [/tex] in each problem below.

1. [tex]6 \times (5 \times \, ?) = (6 \times 5) \times 12 \qquad ? = 12[/tex]

2. [tex](? \times 9) \times 3 = 16 \times (9 \times 3) \qquad ? = 16[/tex]

3. [tex](5 \times 8) \times 10 = 5 \times (? \times 10) \qquad ? = 8[/tex]

4. [tex]2 \times (? \times 6) = (2 \times 14) \times 6 \qquad ? = 14[/tex]

5. [tex](? \times 6) \times 11 = 9 \times (6 \times 11) \qquad ? = 9[/tex]

6. [tex]5 \times (5 \times \, ?) = (5 \times 5) \times 8 \qquad ? = 8[/tex]

7. [tex](14 \times \, ?) \times 6 = 14 \times (3 \times 6) \qquad ? = 3[/tex]

8. [tex]20 \times (4 \times 7) = (? \times 4) \times 7 \qquad ? = 20[/tex]
