Question

помогите пожалуйста с решением

Answer 1

= (3-1)+(4/9-1/6) = 2+(8/18- 3/18) = 2+5/18 = 2  5/18
= (6-1)+(7/8-1/12) = 5+(21/24-2/24) = 5 + 19/24 = 5  19/24
= (5 - 1) + (1/5-1/20) = 4 + (4/20-1/20)= 4 + 3/20 = 4  3/20
= (7+1) + (3/8 + 3/10)= 8 + (15/40+12/40) = 8+27/40 = 8  27/40
= (9-2) +(5/6-3/8) = 7 +(20/24-9/24) = 7+ 11/24 = 7  11/24
= (10 + 2) + (3/4+1/6) = 12+(9/12 +2/12) = 12+11/12 = 12  11/12
= (9 -1) + (3/5 - 1/10) = 8 +(6/10-1/10)= 8 + 5/10 = 8  5/10 = 8  1/2
