Answer 1

1 1/2-2/3=3/2-2/3=9/6-4/6=5/6
1 1/4-1/3=5/4-1/3=15/12-4/12=11/12
1 1/8-1/4=9/8-1/4=9/8-2/8=7/8
1 2/3-5/6=5/3-5/6=10/6-5/6=5/6
2 3/10-4/15=23/10-4/15=69/30-8/30=61/30=2 1/30
3 1/4-5/6=13/4-5/6=39/12-10/12=29/12=2 5/12

Answer 2

а) 1 + 1/2 - 2/3 = 1 + 3/6 - 4/6 = 1 - 1/6 = 5/6

б) 1 + 1/4 - 1/3 = 1 + 3/12 - 4/12 = 1 - 1/12 = 11/12

в) 1 + 1/8 - 1/4 = 1 + 1/8 - 2/8 = 1 - 1/8 = 7/8

г) 1 + 2/3 - 5/6 = 1 + 4/6 - 5/6 = 1 - 1/6 = 5/6

д) 2 + 3/10 - 4/15 = 2 + 9/30 - 8/30 = 2 + 1/30 = 61/30

е) 3 + 1/4 - 5/6 = 3 + 3/12 - 10/12 = 3 - 7/12 = 29/12
