выделите целую часть из дробей ) 20/7, б) 38/6, в) 13/7

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.
