Question

Calculati,DAU FUNDA !!!
c)[ 1,(2) + 1,0(2) ] [2,3(1) - 0,0(6) 0,0(6)^{3} =


d)5,3(5) + 8,0(9) + 0,(6) : 0,(1)=
e)(8,2 -5,42 ) : 3,5 +2,4 : 0,25 +5,(6)=

Answer 1

d)5,3(5)=(535-53)/90=482/90=simplificam=241/45
8,0(9)=(809-80)/90=729/90=243/30=81/10
0,(6)=6/9=2/3
0,(1)=1/9
5,3(5) + 8,0(9) + 0,(6) : 0,(1)=
241/45+81/10+2/3:1/9
(241x10+81x45)/450+2/3x9/1=
6055/450+6=(6055+450x6)/450=8755/450=1751/90=19,4(5)

e)5,(6)=(56-5)/9=51/9=17/3
(8,2 -5,42 ) : 3,5 +2,4 : 0,25 +5,(6)=
2,78:3,5+2,4:0,25+17/3=
278/100:35/10+24/10:25/100+17/3=
278/100x10/35+24/10x100/25+17/3= simplificam ce se poate=
139/5x1/35+240/25+17/3=
139/175+48/5+17/3=
(139x3+48x105+17x175)/525=
(417+5040+2975)/525=8432/525\
