Jawaban:

2) 9/10 – 2/5 + 3/4

= 18/20 – 8/20 + 15/20

= 25/20

= 1 5/20= 1 1/4

4) 2 2/3 + 4 3/5 – 4/15

= 8/3 + 23/5 – 4/15

= 40/15 + 69/15 – 4/15

= 105/15 = 7

5) 8 8/9 – 2 1/6 – 1/2

= 80/9 – 13/6 – 1/2

= 320/36 – 78/36 – 18/36

= 224/36 = 6 8/36 = 6 4/18

3) 10 5/8 – 4 5/12 + 2 3/4

= 85/8 – 53/12 + 11/4

= 255/24 – 106/24 + 66/24

= 185/24= 7 17/24
