(4.8b-0.6bc-1.5bd): (0.3b)

Решите задачу:

$(4.8b - 0.6bc - 1.5bd) \div (0.3b) \\ \\ \frac{(24}{5} b - \frac{3}{5} bc - \frac{3}{2} bd) \div ( \frac{3}{10} b) \\ \\ \frac{2 \times 24b}{2 \times 5} - \frac{2 \times 3bc}{2 \times 5} - \frac{5 \times 3bd}{5 \times 2} \\ \\ \frac{48b - 6bc - 15bd}{10} \div \frac{ 3b}{10} \\ \\ \frac{3b \times (16 - 2c - 5d)}{10} \times \frac{10}{3b} \\ \\ 16 - 2c - 5d$
