pliss bntu jwb,thanks

1. 5/8 + 0,6 = 5/8 + 6/10 = 50/80 + 48/80 = 98/80 = 49/40
2. 0,8 + 3/4 = 8/10 + 3/4 = 20/40 + 30/40 = 70/40
3. 1,6 + 4/20 = 16/10 + 4/20 = 32/20 + 4/20 = 36/20 = 9/5
4. 8/25 + 2,5 = 8/25 + 25/10 = 32/100 + 250/100 = 282/100 = 141/50.
5. 3/5 + 0,4 = 3/5 + 4/10 = 6/10 + 4/10 = 10/10 = 1
maaf kalo salah..
