Tolong bantunya contohnya seperti ini 7 1/2 + 5 1/4 = 12+(1/2+1/4) =12+(2/4+1/4) =12+3/4 =12 3/4

2. 3 3/9 + 8 2/6 = 30/9 + 50/6 = 180/54 + 450/54 = 630/54 = 35/3 = 11 2/3

3. 4 5/6 + 9 2/3 = 29/6 + 29/3 = 29/6 + 58/6 = 87/6 = 29/2 = 14 1/2

4. 3/8 + 1 2/3 + 6 3/4 = 3/8 + 5/3 + 27/4 = 9/24 + 40/24 + 162/24 = 211/24 = 8 19/24

5. 2 1/4 + 3 2/3 + 4 3/5 = 9/4 + 11/3 + 23/5 = 135/60 + 220/60 + 276/60 = 631/60 = 10 31/60

6. 4 5/8 + 4 1/6 = 37/8 + 25/6 = 111/24 + 100/24 = 211/24 = 8 19/24

7. 1 1/4 + 2 1/6 + 7 1/10 = 5/4 + 13/6 + 71/10 = 75/60 + 130/60 + 426/60 = 631/60 = 10 31/60

8. 6 1/5 + 6 11/20 = 31/5 + 131/20 = 124/20 + 131/20 = 255/20 = 51/4 = 12 3/4

9. 2 1/8 + 4 1/12 + 8 7/24 = 17/8 + 49/12 + 199/24 = 51/24 + 98/24 + 199/24 = 348/24 = 29/2 = 14 1/2

10. 3 5/12 + 8 1/4 = 41/12 + 33/4 = 41/12 + 99/12 = 140/12 = 35/3 = 11 2/3
