Пошаговое объяснение:
№1
а) 2 1/5 = (2*5 + 1)/5 = (10+1)/5 = 11/5
б) 3 5/6 = (3*6 + 5)/6 = (18+5)/6 = 23/6
в) 25 3/5 = (25*5 + 3)/5 = (125+3)/5 = 128/5
г) 9 3/10 = (9*10 + 3)/10 = (90+3)/10 = 93/10
№2
а) 31/6 = 31 : 6 = 5 (ост 1)
31/6 = 5 1/6
б) 35/4 = 35 : 4 = 8 (ост 3)
35/4 = 8 3/4
в) 253/10 = 253 : 10 = 25 (ост 3)
253/10 = 25 3/10
г) 47/5 = 47 : 5 = 9 (ост 2)
47/5 = 9 2/5
