Вопрос:

1. Вычисли. 4 · 6 = ? 8 · 6 = ? 9 · 4 = ? 7 · 3 = ? 20 : 5 = ? 28 : 4 = ? 32 : 4 = ? 45 : 9 = ? 3 · 9 = ? 5 · 8 = ? 6 · 7 = ? 3 · 6 = ?

Ответ:

1. Вычисления:

  1. \( 4 \times 6 = 24 \)
  2. \( 8 \times 6 = 48 \)
  3. \( 9 \times 4 = 36 \)
  4. \( 7 \times 3 = 21 \)
  5. \( 20 \div 5 = 4 \)
  6. \( 28 \div 4 = 7 \)
  7. \( 32 \div 4 = 8 \)
  8. \( 45 \div 9 = 5 \)
  9. \( 3 \times 9 = 27 \)
  10. \( 5 \times 8 = 40 \)
  11. \( 6 \times 7 = 42 \)
  12. \( 3 \times 6 = 18 \)

Ответ: 24, 48, 36, 21, 4, 7, 8, 5, 27, 40, 42, 18.
