Question

Найди разность и запиши 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

Answer 1

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=2/31
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
