Найдите разность и запишите ответ в виде несократимой дроби : 11/12 - 1/6 , 5/36 - 1/9 , 19/20 - 4/5 , 5/7 - 3/14 , 20/63 - 2/9 , 11/24 - 5/12 , 5/18 - 1/6 , 1/4 - 3/16

11/12 - 1/6 = (11-2)/12 = 9/12 = 3/4
5/36 - 1/9 = (5-4)/36 = 1/36
19/20 - 4/5 = (19-16)/20 = 3/20
5/7 - 3/14 = (10-3)/14 = 7/14 = 1/2
20/63 - 2/9 = (20-14)/63 = 6/63 = 2/21
11/24 - 5/12 = (11-10)/24 = 1/24
5/18 - 1/6 = (5-3)/18 = 2/18 = 1/9
1/4 - 3/16 = (4-3)/16 = 1/16
