1. 5/8 + 8/10 + 23/5 = 25/40 + 32/40 + 184/40 = 214/40 = 5 14/40 = 5 7/20

1. 5 per 8 +0,8+23 per 5 =
5/8+8/10+23/5= 25/40+ 32/40+ 184/40= 241/40
 = 6 1/40 atau 6.025

2. 3 per 6 + 45 persen +15 per 50
3/6 + 45/100 + 15/50= 
150/300 + 135/300 + 90/300= 375/300 atau 1 75/300 atau 1.25
jika angkanya 43 per 6 + 45 persen +15 per 50
maka:
43/6+45/100 + 15/50=
2150/300 + 135/300 + 90/300= 2375/300 atau 7 275/300
