50 : 10 * 3 = 15 9 : 3 * 7 = 23 6 : 2 * 8 = 24 4 : 2 * 10 = 20 60 : 10 : 3 = 3

Решение:

1. \( 50 : 10 \times 3 = 5 \times 3 = 15 \)
2. \( 9 : 3 \times 7 = 3 \times 7 = 21 \)
3. \( 6 : 2 \times 8 = 3 \times 8 = 24 \)
4. \( 4 : 2 \times 10 = 2 \times 10 = 20 \)
5. \( 60 : 10 : 3 = 6 : 3 = 2 \)

Ответ: 15, 21, 24, 20, 2.
