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

6. 2/3 x 1 5/9 =
= 2/3 x 14/9
= (2 x 14)/(3 x 9)
= 28/27
= 1 1/27

7. 2/5 x 1 3/7 =
= 2/5 x 10/7
= (2 x 10)/(5 x 7)
= 20/35
= 4/7

8. 3/4 x 2 3/10 =
= 3/4 x 23/10
= (3 x 23)/(4 x 10)
= 69/40
= 1 29/40
