Answer 2

1.-simplificamos
=8/4+6/3-3/8
=2+2-3/8
=4-3/8
=(32-3)/8
=29/8
2.-12/6+8/4-3/7
=2+2-3/7
= 4-3/7
=(28-3)/7
=25/7
3.-6/2+9/3-3/7
=3+3-3/7
=(6-3)/7
=39/7
4.-18/9+12/3-5/4
=2+4-5/4
=6-5/4
=(24-5)/4
=19/4
5.-10/5+4/2-4/5
=2+2-4/5
=4-4/5
=(20-4)/5
=16/5
6.-20/4+15/5-4/10
=5+3-4/10
=8-4/10
=(80-4)/10
=76/10 simplificamos por 2
=38/5
7.-16/8+8/2-6/9
=2+4-6/9
=6-6/9
=(54-6)/9
=48/9simplicamos por 3
=16/3
