tolong ya kak 1 , 2/5 + 3/8×1/2 2. 3/4+1/3:1/4 3. 2/3 - 1/6 :8/5

1. 2/5 + 3/8 . 1/2
3/8 . 1/2 = 3/16
2/5 + 3/16 = 32+15/80 = 47/80

2. 3/4 + 1/3 : 1/4
1/3 : 1/4 = 1/3 . 4/1 = 4/3
3/4 + 4/3 = 9+16/12 = 25/12 = 2 1/12

3. 2/3 - 1/6 : 8/5
1/6 : 8/5 = 1/6 . 5/8 = 5/48
2/3 - 5/48 = 32-5/48 = 27/48 = 9/16

maaf kalo salah
