Jawaban:

1. 4 3/6 + 2 4/5

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

= 6 [(3 x 5)/30 + (4 x 6)/30)]

= 6 [15/30 + 24/30]

= 6 [39/30]

= 6 + 1 9/30

= 7 9/30

= 7 3/10

2. 3 2/7 + 3 3/6

= 23/7 + 21/6

= (23 x 6)/42 + (21 x 7)/42

= 138/42 + 147/42

= 285/42

= 6 33/42

= 6 11/14

3. 6 3/4 - 1 4/5

= 27/4 + 9/5

= (27 x 5)/20 + (9 x 4)/20

= 135/20 + 36/20

= 171/20

= 8 11/20

4. 8 2/6 - 2 3/4

= 50/6 - 11/4

= (50 x 2)/12 - (11 x 3)/12

= 100/12 - 33/12

= 67/12

= 5 7/12

5. 7 1/4 - 1 5/7 + 2 3/5

= 29/4 - 12/7 + 13/5

= (29 x 35)/140 - (12 x 20)/140 + (13 x 28)/140

= 1.015/140 - 240/140 + 364/140

= 1.139/140

= 8 19/140
