Please answer the question from the attachment.

Answer 1

A) 4/3+5/3-1/2
mmc= 6
8+10-3= 15/6
simplifica
resposta= 5/2
B) 2/5+1/4-1/10
mmc=20
8+5-2= 11/20
resposta= 11/20
C)[1-(1/6-1/3)]/[(1/6+1/2)^2+3/2]
primeira parte
mmc=6
(6-1+2)/6=7/6
segunda parte
mmc=6
(1/6+1/2)^2= (1/6+3/6)^2=(4/6)^2=(2/3)^2=4/9
terceira parte
mmc=18
4/9+3/2= 8/18+27/18=35/18
4 parte
(7/6)/(35/18)=(7/6)*(18/35)
simplifica
(1/1)*(3/5)
resposta =3/5
