1. hitunglah :
a) 4 2/3 + 5/27 = 14/3+5/27 = 126/27+5/27 = 131/27 = 4 23/27

b) 4 1/4 - 3/20 = 17/4 - 3/20 = 85/20 - 3/20 = 82/20 = 4 2/20 = 4 1/10

c) 1 2/3 + 10 1/4 -5/8 = 5/3+ 41/4 - 5/8 = 40/24 + 246/24 - 15/24 = 271/24 = 11 7/24
d) 1/3 + 7/15 : 1/3 = 1/3+7/15×3/1 = 1/3+21/15 = 5/15 + 21/15 = 26/15 = 1 11/15

2. Urutan dari yg trendah
1/6 , 3/4 , 5/8
4/24 ; 18/24 ; 15/24
4/24(1/6) ;15/24(5/8) ;18/24(3/4)
Jadi,urutannya ialah 1/6 ; 5/8 ; dan 3/4
