1. Вычисли. 4 * 18 = 90 : 5 = 2 * 34 = 60 : 4 = 96 : 4 = 5 * 17 = 99 : 9 = 4 * 24 = 3 * 26 = 65 : 5 =

Решение:

1. \( 4 \cdot 18 = 72 \)
2. \( 90 : 5 = 18 \)
3. \( 2 \cdot 34 = 68 \)
4. \( 60 : 4 = 15 \)
5. \( 96 : 4 = 24 \)
6. \( 5 \cdot 17 = 85 \)
7. \( 99 : 9 = 11 \)
8. \( 4 \cdot 24 = 96 \)
9. \( 3 \cdot 26 = 78 \)
10. \( 65 : 5 = 13 \)

Ответ: 72, 18, 68, 15, 24, 85, 11, 96, 78, 13.
