Answer 1

(3 5\6-2\6)+4 = 3 3/6 + 4=
Сокращаем 3/6 на 3
3 1/2+ 4= 7 1/2= 7,5


2 1\7+(4\7+1 2\7)=2 1/7+ 1 6/7= 3 7/7= 4


6 2\5-(1 3\5-1\5)= 6 2/5- 1 2/5= 5


(3 7\8+1\8)-2 5\8= 3 8/8- 2 5/8= 1 3/8


7\9+(1 2\9-5\9)= 7/9+ 1 2/9 - 5/9=
(7/9- 5/9)+ 1 2/9= 2/9+ 1 2/9= 1 4/9


(4 2\5+4\5)+1 4\5= 4 6/5+ 1 4/5=
5 10/5= 7


6 1\4-(3 2\4+1 1\4) = 6 1/4 - 3 2/4- 1 1/4=
(6 1/4- 1 1/4) - 3 2/4= 5 - 3 2/4=
4 4/4- 3 2/4= 1 2/4= 1 1/2 = 1,5


(5-2 3\8)-7\8= 5 - (2 3/8+ 7/8)=
5- 2 10/8= 5 -3 2/8= 5 - 3 1/4=
4 4/4- 3 1/4= 1 3/4 = 1,75
