Answer 1

А) 1/2 - 2/5 = (5/10) - (4/10) = 1/10 Б) 1/4 - 1/5 = (5/20) - (4/20) = 1/20 С) 3/5 - 2/7 = (21/35) - (10/35) = 11/35 Д) 8/9 - 7/15 = (120/135) - (63/135) = 57/135 = 19/45 Е) 7/11 - 4/7 = (49/77) - (44/77) = 5/77 Ф) 19/20 - 13/15 = (57/60) - (52/60) = 5/60 = 1/12 Г) 11/18 - 11/30 = (55/90) - (33/90) = 22/90 = 11/45 Х) 17/24 - 19/60 = (85/120) - (38/120) = 47/120
