б)7/8*14/15*5/7*32/45*3/35*9/8*5/6

Answer 1

Ответ:

Пошаговое объяснение:

А) = (5/3 * 9/15) * (10/16 * 16/20) * (4/7 * 14/4) * (33/14 * 7/16) =

(1/1 * 3/5) * (1/1 * 1/2) * (1/1 * 2/1) * (33/2 * 1/16) =

3/5 * 1/2 * 2 * 33/32 =

3/10 * 2 * 33/32 = 6/10 * 33/32 = 3/10 * 33/16 = 99/160

Б) = (7/8 * 3/35) * (14/15 * 5/7) * (32/45 * 9/8) * (5/7 * 5/6) =

(1/8 * 3/5) * (2/3 * 1/1) * (4/5 * 1/1) * 25/42 =

3/40 * 2/3 * 4/5 * 25/42 =

1/20 * 1/1 * 2/1 * 5/21 =

1/20 * 10/21 = 1/2 * 1/21 = 1/42
