Пошаговое объяснение:
а) 4/9 : 7/8 = 4/9 * 8/7 = (4*8)/(9*7) = 32/63
б) 6/25 : 12/35 = 6/25 * 35/12 = 1/5 * 7/2 = 7/10
в) 14/41 : 7 = 14/41 * 1/7 = 2/41 * 1/1 = 2/41
г) 100 : 20/23 = 100 * 23/20 = 5 * 23/1 = 115/1 = 115
5 1/3 : 2 2/3 = 16/3 : 8/3 = 16/3 * 3/8 = 2/1 * 1/1 = 2/1 = 2
е) 6 5/6 : 1 5/6 = 41/6 : 11/6 = 41/6 * 6/11 = 41/1 * 1/11 = 41/11 = 3 8/11
