Выделим целую часть из дробей:

а) 20/7 = (14 + 6) / 7 = 14/7 + 6/7 = 2 + 6/7 = 2 6/7;

б) 38/6 = (36 + 2) / 6 = 36/6 + 2/6 = 6 + 2/6 = 6 + 1/3 = 6 1/3;

в) 13/7 = (7 + 6) / 7 = 7/7 + 6/7 = 1 + 6/7 = 1 6/7;

г) 30/4 = (28 + 2) / 4 = 28/4 + 2/4 = 7 + 2/4 = 7 + 1/2 = 7 1/2;

д) 48/5 = (45 + 3) / 5 = 45/5 + 3/5 = 9 + 3/5 = 9 3/5;

е) 19/7 = (14 + 5) / 7 = 14/7 + 5/7 = 2 + 5/7 = 2 5/7;

ж) 58/5 = (55 + 3) / 5 = 55/5 + 3/5 = 11 + 3/5 = 11 3/5;

з) 203/10 = (200 + 3) / 10 = 200/10 + 3/10 = 20 + 3/10 = 20 3/10;

и) 22/4 = (20 + 2) / 4 = 20/4 + 2/4 = 5 + 1/2 = 5 1/2;

к) 78/6 = 13.
