= 9/5 x 2
= (9 x 2)/5
= 18/5
= 3 3/5

3. 2 5/8 x 6
= 21/8 x 6
= (21 x 6)/8
= 126/8
= 15 6/8
= 15 3/4

4. 1 5/7 x 4 =
= 12/7 x 4
= (12 x 4)/7
= 48/7
= 6 6/7

5. 1 7/9 x 2 =
= 16/9 x 2
= (16 x 2)/9
= 32/9
= 3 5/9

Soal Ayo mencoba kerjakan perkalian pecahan campuran dengan pecahan biasa, berikut jawabannya

1. 2 2/3 x 1/6 =
= 8/3 x 1/6
= (8 x 1)/(3 x 6)
= 8/18
= 4/9

2. 2 4/5 x 1/8 =
= 14/5 x 1/8
= (14 x 1)/(5 x 8)
= 14/40
= 7/20

3. 1 2/7 x 2/5 =
= 9/7 x 2/5
= (9 x 2)/(7 x 5)
= 18/35

4. 1 2/7 x 2/3 =
= 9/7 x 2/3
= (9 x 2)/(7 x 3)
= 18/21 = 6/7

5. 1 7/8 x 2/5 =
= 15/8 x 2/5
= (15 x 2)/(8 x 5)
= 30/40
= 3/4
