Answer 1

3 1/4 - 2 3/5 + 1 7/10 =13/4-13/5+1 7/10=13/20+17/10=47/20=2 7/20
4 1/6 - 1 3/5 + 2 1/2 =25/6-8/5+2 1/2=77/30+5/2=76/15=5 1/15
1 5/9 + 2 1/3 + 3 1/6 =14/9+7/3+3 1/6=35/9+19/6=127/18=7 1/18
7/8 + 2 1/6 + 1 3/4 =7/8+13/6+1 3/4=73/24+7/4=115/24=4 19/24

Answer 2

1)=155/20-92/20+34/20=97/20=4 17/20
2)=205/30-78/30+315/30=437/30=14 17/30
3)=30/18+126/18+93/18=249/18=13 15/18
4)=21/24+84/24+68/24=173/24=7 5/24
