Answer 1

(1,5+1/3)÷[0,(6)+6,(6)]=
=(3/2+1/3)÷[6/9+(66-6)/9]=
=(9+2)/6 ÷(2/3+60/9)=
=11/6 ÷(2/3+20/3)=
=11/6 ÷22/3=
=11/6 ×3/22=
=1/4=0,25


[3/4-0,(3)]²÷0,25=
=(3/4-1/3)²:1/4=
=[(9-4)/12]²×4=
=(5/12)²×4=
=25/144×4=
=25/36=0,69(4)



(0, 5)² /0,(6) +1- 22/27 -0,375=
=(1/2)² /(2/3) +1- 22/27 -375/1000=
=1/4 ×3/2 +1- 22/27 -3/8=
=3/8 +1- 22/27 -3/8=
=1- 22/27=
=(27-22)/27=5/27=0,(185)
