6. 5/6 x 4/11 = (5x4)/(6x11) = 20/66 = 10/33
7. 3/4 x 3/14 = (3x3)/(4x14) = 9/56
8. 5/6 x 9/17 = (5x9)/(6x17) = 45/102 = 15/34
9. 4/11 x 4/7 = (4x4)/(11x7) = 16/77
10. 2/9 x 3/23 = (2x3)/(9x23) = 6/207 = 2/69
Kerjakan perkalian pecahan biasa dengan bilangan asli berikut!
1. 5 x 2/3 = (5 x 2)/3 = 10/3 = 3 1/3
2. 8 x 1/4 = (8 x 1)/4 = 8/4 = 2
3. 3 x 2/5 = (3 x 2)/5 = 6/5 = 1 1/5
4. 6 x 5/12 = (6 x 5)/12 = 30/12 = 5/2 = 2 1/2
5. 12 x 7/9 = (12 x 7)/9 = 84/9 = 28/3 = 9 1/3
6. 6/5 x 4 = (6 x 4)/5 = 24/5 = 4 4/5
7. 3/4 x 20 = (3 x 20)/4 = 60/4 = 15
8. 1/6 x 12 = (1 x 12)/6 = 12/6 = 2
9. 4/11 x 8 = (4 x 8)/11 = 32/11 = 2 10/11
10. 2/9 x 5 = (2 x 5)/9 = 10/9 = 1 1/9
