= 15/12 = 1 3/12
= 1 1/4

2. 9/10 – 2/5 + 3/4 =
=18/20 – 8/20 + 15/20
= 25/20 = 5/4
= 1 1/4

3. 1 3/5 + 2 1/6 – 1/2 =
= 1 18/30 + 2 5/30 – 15/30
= 3 23/30 – 15/30 = 3 8/30
= 3 4/15

4. 2 2/3 + 4 3/5 – 4/15 =
=2 10/15 + 4 9/15 – 4/15
= 6 19/15 – 4/15
= 6 15/15
= 7

5. 8 8/9 – 2 1/6 – 1/2 =
= 8 16/18 – 2 3/18 – 9/18
= 6 13/18 – 9/18
= 6 4/18
= 6 2/9

6. 12 5/6 – 2 1/6 – 1/2 =
= 12 5/6 – 2 1/6 – 3/6
= 10 4/6 – 3/6
= 10 1/6

7. 15 9/11 + 2 1/22 – 1 1/2 =
= 15 18/22 + 1 1/22 – 1 11/22
= 16 19/22 – 1 11/22
= 15 18/22
= 15 9/11

8. 20 2/3 + 2 3/5 – 2 2/15 =
= 20 10/15 + 2 9/15 – 2 2/15
= 22 1/15 – 2 2/15
= 21 16/15 – 2 2/15
= 19 14/15

9. 24 8/9 – 12 1/6 – 3 1/2 =
= 24 16/18 – 12 3/18 – 3 9/18
= 12 13/18 – 3 9/18 = 9 4/18
= 9 2/9

10. 50 5/6 – 5 5/12 – 4 1/8 =
= 50 20/24 – 5 10/24 – 4 3/24
