Б) 5/9*3b*2/5

Answer 1

Ответ:

Пошаговое объяснение:

a)2 3/8*3/9*1 1/9a = 19/8 * 1/3 * 10/9 a = 19/8 * 10/27 a = 95/108 a

Б) 5/9*3b*2/5 = 5/3 b * 2/5 = 2/3 b

Answer 2

а)$2 \frac{3}{8} \times \frac{3}{9} \times 1 \frac{1}{9} a = \frac{19}{8} \times \frac{1}{3} \times \frac{10}{9} a = \frac{19}{8} \times \frac{10}{27} a = \frac{95}{108} a$

Б)$\frac{5}{9} \times 3b \times \frac{2}{5} = \frac{5}{3} b \times \frac{2}{5} = \frac{2}{3} b$
