Penjelasan dengan langkah-langkah:

1.

8 3/4 – 6 2/6 =

35/4 – 38/6 =

105/12 – 76/12 =

29/12 = 2 5/12

2.

4 5/6 – 1 3/4 =

29/6 – 7/4 =

58/12 – 21/12 =

37/12 = 3 1/12

3.

6 4/5 – 3 1/3 =

34/5 – 10/3 =

102/15 – 50/15 =

52/15 = 3 7/15

4.

7 3/4 – 1 1/5 =

31/4 – 6/5 =

155/20 – 24/20 =

131/20 = 6 11/20

5.

5 2/3 – 2 2/5 =

17/3 – 12/5 =
