Penjelasan dengan langkah-langkah:

Jika ada pecahan yang berbeda, maka disamakan terlebi dahulu.

1. 6 1/4 - 1 1/3

= 6 3/12 - 1 4/12

= 4 11/12

2. 4 5/8 - 2 7/16

= 4 10/16 - 2 7/16

= 2 3/16

3. 12 5/7 - 3 5/6

= 12 30/42 - 3 35/42

= 8 37/42

4. 15 3/8 - 5 2/3

= 15 9/24 - 5 16/24

= 9 7/24

5. 17 5/12 - 9 4/5

= 17 25/60 - 9 48/60

= 7 37/60

6. 2 2/3 + 1 5/8

= 2 16/24 + 1 15/24

= 3 31/24

= 4 7/24

7. 2 1/6 + 3 1/9 + 5 7/36

= (2 6/36 + 3 4/36) + 5 7/36

= 2 10/36 + 5 7/36

= 7 17/36

8. 3 1/3 + 4 1/4 + 5 1/5

= (3 4/12 + 4 2/12) + 5 1/5

= 7 6/12 + 5 1/5

= 7 30/60 + 5 12/60

= 7 15/30 + 5 6/30

= 12 31/30

= 13 1/30

9. 6 7/12 + 7 6/7 + 8 11/21

= (6 49/84 + 7 72/84)

= 14 37/84 + 8 11/21

= 14 651/1764 + 8 924/1764

= 22 1575/1764

10. 4 5/6 + 8 4/15 + 1 5/9

= (4 25/30 + 8 8/30) + 1 5/9

= 13 3/30 + 1 5/9

= 13 27/270 + 1 150/270

= 14 177/270
