Ответ:
Пошаговое объяснение:
1) 1/4 + 5/6=6/24+20/24=26/24=1 1/12
2) 3/20+7/25 =15/100+28/100=43/100
3) 2/9+1/6 =4/18+3/18=7/18
4) 5/6-3/8 =20/24-9/24=11/24
5) 9/10-3/4 =18/20-15/20=3/20
6) 3/10-2/15=9/30-4/30=5/30=1/6

б) 7/4 = 28/16 = 84/48 = 168/96
№659
б) 1/4 = 3/12 = 4/16 = 5/20 = 7/28 = 15/60
г) 5/6 = 10/12 = 25/30 = 30/36 = 50/60 = 55/66

б) 2/7 = 4/14 = 6/21 = 10/35 = 40/140
