Question

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

Answer 1

(4.8b-0.6bc-1.5bd): (0.3b)= 4,8b:0,3b-0,6bc:0,3b-1,5bd:0,3b= 16-2c-5d

Answer 2

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