Cara/Penjelasan
1. 2/9 + 4/5
= 10/45 + 4/5
= 10/45 + 36/45
= 46/45
= 1 1/45
2. 4/6 + ⅔
= ⅔ + ⅔
= 4/3
= 1 ⅓
3. 5/7 + 2/5
= 25/35 + 2/5
= 25/35 + 14/35
= 39/35
= 1 4/35
4. ⅞ + 4/6
= ⅞ + ⅔
= 21/24 + ⅔
= 21/24 + 16/24
= 37/24
= 1 13/24
5. 3 1/10 + 4 2/4
= 31/10 + 4 2/4
= 31/10 + 9/2
= 38/5
= 7 3/5
6. 4 3/7 + 5 8/9
= 31/7 + 5 8/9
= 31/7 + 53/9
= 650/63
= 10 20/63
7. ⅝ + 3 5/7
= ⅝ + 26/7
= 243/56
= 4 19/56
8. 2 ½ + 3 ¼
= 5/2 + 3 ¼
= 5/2 + 13/4
= 23/4
= 5 ¾
9. 1 ⅝ + 2 6/9
= 13/8 + 2 6/9
= 13/8 + 8/3
= 103/24
= 4 7/24
10. 3 4/7 + 4/6
= 25/7 + 4/6
= 89/21
= 4 5/21
