Answer 1

1 - 2\3 = 3\3 - 2\3 = 1\3
1 - 23\30 = 30\30 - 23\30 = 7\30
1 - 2\5 = 5\5 - 2\5 = 3\5
1 - 7\10 = 10\10 - 7\10 = 3\10

Answer 2

1-2/3=1/3;1-23/30=7/30;1-2/5=3/5;1-7/10=3/10

Answer 3

1 - 2/3 = 1 - 0.6667 = 0.3333 1 - 23/30 = 1 - 0.7667 = 0.2333 1 - 2/5 = 1 - 0.4 = 0.6 1 - 7/10 = 1 - 0.7 = 0.3
