Tolong ya kak No 1-10sama caranya

1. 72/128 : 4 = 18/32 : 2 = 9/16
2. 5 1/5 + 2 2/3 = 26/5 + 8/3 = 118/15 = 7 13/15
3. 7/8 5/6 2/3 3/5 (SORRY GK PAKE CARA :V)
4. 3 1/8 : 0,125 = 25/8 : 125/1000 = 25000/1000 = 25
5. 7 3/4 – 4 2/5 = 31/4 – 22/5 = 155/20 – 88/20 = n = 67/20 = 3 7/20
cuma 1 – 5 aja hehehehe…
