9/8 = 8/8 + 1/8
= 1 + ⅛
= 1⅛

3. Ayo, urutkan pecahan-pecahan di dalam kurung ( ) dari yang terbesar.

1.) (2/7, 5/7, 6/7, 4/7)
Jawaban:
= 6/7, 5/7, 4/7, 2/7

2.) (1/6, 1/8, 1/5, 1/10)
Jawaban:
= 20/120, 15/120, 24/120, 12/120
= 24/120, 20/120, 15/120, 12/120
= 1/5, 1/6, 1/8, 1/10.

3.) (2⅛, 2 5/8, 2 7/8, 2 3/8)
Jawaban:
= 2 7/8, 2 5/8, 2 3/8, 2 1/8.

4.) (3 2/9, 1 5/9, 2 7/9, 4 1/9)
Jawaban:
= 4 1/9, 3 2/9, 2 7/9, 1 5/9

4. Ayo, hitung hasil penjumlahan bilangan berikut.

1.) 3/5 + 2/5
Jawaban:
= 3/5 + 2/5
= 5/5
= 1

2.) 2 5/9 + 8/9
Jawaban:
= 2 5/9 + 8/9
= 2 + (5/9 + 8/9)
= 2 + 13/9
= 2 + 9/9 + 4/9
= 2 + 1 + 4/9
= 3 4/9

3.) 1 2/7 + 2 2/7
Jawaban:
= 1 2/7 + 2 2/7
= 1 + 2 + (2/7 + 2/7)
= 3 4/7

4.) 4⅔ + 2⅔
Jawaban:
= 4⅔ + 2⅔
= (4 + 2) + (⅔ + ⅔)
= 6 + 4/3
= 6 + 3/3 + ⅓
= 6 + 1 + ⅓
= 7⅓

5.) 3 4/8 - 1 3/8
Jawaban:
= 3 4/8 - 1 3/8
= (3 - 1) + (4/8 + 3/8)
= 2 + ⅛
= 2⅛

6.) 1 5/9 - 7/9
Jawaban:
= 1 5/9 - 7/9
= 9/9 + 5/9 - 7/9
= 14/9 - 7/9
= 7/9

7.) 1 - 7/10
Jawaban:
= 1 - 7/10
= 10/10 - 7/10
= 3/10

8) 4 1/5 - 2 3/5
Jawaban:
= 4 1/5 - 2 3/5
= 3 + 5/5 + 1/5 - 2 3/5
= 3 6/5 - 2 3/5
= 1 3/5
