ответ:1)5/8,9/11,7/9,5/6
2)7/20,5/9,2/3,3/4
3) 1ц2/7, 1ц 13/21, , 1ц 1/2
Пошаговое объяснение:
приводим дроби к общему знаменателю:
1)
5/6 = 660/792,
7/9 = 616/792,
9/11 = 648/792,
5/8 = 495/792, значит:
5/8, 7/9, 9/11, 5/6,
2)
3/4 = 135/180,
7/20 = 63/180,
2/3 = 120/180,
5/9 = 100/180,
7/20, 5/9, 2/3, 3/4,
3)
1 1/2 = 3/2 = 63/42,
1 2/7 = 9/7 = 54/42,
1 13/21 = 34/21 = 68/42,
1 2/7, 1 1/2, 1 13/21
