1.5/2 -( 3/2 + 4/5 )

2.7/8 + ( 1/8 + 1/9 )

3.5/6 + ( 1/2 + 2/3 )

4.9/7 - ( 2/7 - 10/21 )

5.3/7 + 49/9 + 4/7

6.8/9 + 15/36 + 3/27

7.5/2 - ( 3/2 + 4/5 )

8.7/8 + ( 1/8 + 1/9 )

10.1/5 + ( 3/7 + 8/10 )

分数析取:

1.1/3 + 3/4 + 1/5

2.3/8 + 8/3 - 1/2

3.5/6 + 1/12 + 3/4

4.30/46 - 1/2 + 7/23

5.8/11 + 2/6 + 7/33

6.19/8 - 1/2 - 3/4

7.7/25 + 3/10 - 2/5

8.18/121 - 1/2 + 9/11

9.6/17 - 1/51 - 1/34
