a) 2,(3)+2 1/3 +55/33 =3=7/3+7/3+5/3=19/3=6,(3)
2,(3)=(23-2)/9=21/9=7/3
2 1/3 = (2×3+1)/3=7/3
55/33=5/3

b) 4,5 +1,(3)+3 2/5=9/2+4/3+17/5=(9×15+4×10+17×6)/30=(135+40+102)/30=
=277/30=9,2(3)
4,5=45/10=9/2
1,(3)=(13-1)/9=12/9=4/3
3 2/5=(3×5+2)/5=17/5

c) 5/12+ 3 1/6+0,0(6)=5/12+19/6+1/15=(5×5+19×10+1×4)/60=
=(25+190+4)/60=219/60=3,65
3 1/6=(3×6+1)/6=19/6
0,0(6)=6*90=1/15

d)5 1/10+0,7+4 1/2 = 51/10+7/10+9/2 =58/10+9/2=(58+45)/10=103/10=10,3
