Bab Pecahan

1] 1/2 x 2 2/4 x 3 5/8
= 1/2 x 10/4 x 29/8
= 1/2 x 5/4 x 29/8
= 145/64
= 2 17/64

2] 2 2/9 x 2 2/5 x 6/10
= 20/9 x 12/5 x 6/10
= 20/10 x 6/9 x 12/5
= 2 x 2/3 x 12/5
= 2 x 2/5 x 12/3
= 4/5 x 4
= 16/5
= 3 1/5

1. 1/2 x 2 2/4 x 3 5/8
2 2/4 = 10/4
3 5/8 = 29/8
1/2 x 10/4 x 29/8
= 290/64 = 4 34/64
= 4 17/32

2. 2 2/9 x 2 2/5 x 6/10
2 2/9 = 20/9
2 2/5 = 12/5
20/9 x 12/5 x 6/10 = 1440/450
= 3 90/450
= 3 1/5
