Пошаговое объяснение:
Г) 1/4+1/6 = 6/24+4/24 = 10/24 = 5/12
Д) 1/4+5/6 = 6/24+20/24 = 24/24 = 1
Е) 3/4+1/6 = 18/24+4/24 = 22/24 = 11/12
Ё) 3/4+4/5 = 15/20+ 16/20 = 31/20 = 1 11/20
Ж) 1/4+1/8 = 4/16+2/16 = 6/16 = 3/8
З) 1/3+5/6 = 2/6+5/6 = 7/6 = 1 1/6
И) 1/2+3/8 = 4/8+3/8 = 7/8
Й) 3/4+5/12 = 9/12+5/12 = 14/12 = 1 1/6
К) 5/6+7/12 = 10/12+7/12 = 17/12 = 1 5/12
С) 2/7+8/11 = 22/77+56/77 = 78/77 = 1 1/77
У) 1/2+3/7 = 7/14+6/14 = 13/14
Д) 1/2-1/3 = 3/6-2/6 = 1/6
Е) 2/3-1/5 = 10/15-3/15 = 7/15
Ё) 3/10-2/15 = 9/30 - 4/30 = 5/30 = 1/6
7 - 2 = 5
ответ: 7 и 2.
