Jawab:

Nilai tengahnya yaitu 5 & 6 sehingga 5/6 yaitu 0,83

1. 5/9 + 4 2/6

2. 5 1/6 + 9/12

3. 6 1/8 + 10/12

4. 5/8 + 3 3/10

5. 2 3/4 + 4/6

6. 3/12 + 2 4/8

7. 6/8 + 4 3/4

8. 6 2/5 + 7/10

9. 4 1/4 + 7/8

10. 6/10 + 5 1/12

hasilnya berapa?

1) 5/9 + 4 ²/6
= (5/9 × 2/2) + 4(2/6 × 3/3)
= 10/18 + 4 6/18
= 4 16/18
= 4 8/9

2) 5 1/6 + 9/12
= 5 (1/6 × 2/2) + 9/12
= 5 2/12 + 9/12
= 5 11/12

3) 6 1/8 + 10/12
= 6 (1/8 × 6/6) + (10/12 × 4/4)
= 6 6/48 + 40/48
= 6 46/48
= 6 23/24

4) 5/8 + 3 3/10
= (5/8 × 5/5) + 3 (3/10 × 4/4)
= 25/40 + 3 (12/40)
= 3 37/40

5) 2 ¾ + 4/6
= 2 ( ¾ × 3/3) + (4/6 × 2/2)
= 2 9/12 + 8/12
= 2 17/12
= 3 5/12

6) 3/12 + 2 4/8
= (3/12 × 2/2) + 2 (4/8 × 3/3)
= 6/24 + 2 12/24
= 2 18/24
= 2 ¾

7) 6/8 + 4 ¾
= (6/8 × 2/2) + 4(¾ + 4/4)
= 8/16 + 4 12/16
= 4 20/16
= 5 4/16
= 5 ¼

8) 6 2/5 + 7/10
= 6 (2/5 × 2/2) + (7/10 × 1/1)
= 6 4/10 + 7/10
= 6 11/10
= 7 1/10

9)4 ¼ + 7/8
= 4 (¼ × 2/2) + (7/8 × 1/1)
= 4 2/8 + 7/8
= 4 9/8
= 5 1/8

10) 6/10 + 5 1/12
= (6/10 × 6/6) + 5 (1/12 × 5/5)
= 36/60 + 5 5/60
= 5 41/60
