Решение:
- \( 80 : 5 \cdot 4 = 16 \cdot 4 = 64 \)
- \( 96 : 6 \cdot 3 = 16 \cdot 3 = 48 \)
- \( 45 : 3 \cdot 5 = 15 \cdot 5 = 75 \)
- \( 68 : 4 \cdot 3 = 17 \cdot 3 = 51 \)
- \( 51 : 3 \cdot 5 = 17 \cdot 5 = 85 \)
- \( 78 : 6 \cdot 2 = 13 \cdot 2 = 26 \)
- \( 84 : 4 \cdot 3 = 21 \cdot 3 = 63 \)
- \( 65 : 5 \cdot 6 = 13 \cdot 6 = 78 \)
Ответ: 64, 48, 75, 51, 85, 26, 63, 78.
