Penyelesaian :

1. 8 + 1 5/8.

= 8/1 + 13/8.

= 8×8/1×8 + 13/8.

= 64/8 + 13/8.

= 77/8.

= 9 5/8 ✔

2. 6 + 2 2/4.

= 6/1 + 10/4.

= 6×4/1×4 + 10/4.

= 24/4 + 10/4.

= 34/4.

= 17/2.

= 8 1/2 ✔

3. 3 + 1 2/6.

= 3/1 + 8/6.

= 3×6/1×6 + 8/6.

= 18/6 + 8/6.

= 26/6.

= 13/3.

= 4 1/3 ✔

4. 12 + 2 1/5.

= 12/1 + 11/5.

= 12×5/1×5 + 11/5.

= 60/5 – 11/5.

= 49/5.

= 9 4/5 ✔

5. 9 + 1 4/5.

= 9/1 + 9/5.

= 9×5/1×5 + 9/5.

= 45/5 – 9/5.

= 36/5.

= 7 1/5 ✔

Jawaban:

1.8+ 1 5/8

=8+ 13/8

= 9.625 atau 77/8

2.6+2 2/4

=6 + 5/2

=8.5 atau 17/2

3.3+ 1 2/6

=3+ 4/3

=13/3 atau bisa jadi pecahan campuran 4 1/3

4.12-2 1/5

=12 – 11/5

=9.8 atau 49/5

5.9 – 1 4/5

=9 – 9/5

=7.2 atau 36/5
