Explicație pas cu pas:
a/2=b/2,(1)=c/2,0(6)= (a+b+c)/(2+2,(1) +2,0(6))=320/(2+2,(1) +2,0(6))
2+2,(1) +2,0(6)=2+2si1/9+2si6/90=6+1/9+6/90=6+10/90+6/90=6+16/90=
=6+8/45=278/45=6,1(7)
320: 6,1(7)=51,79856(5179856)=k
a=2k≅103,597
b=2,(1) k=109,352517...≅109,352
c=2,0(6)k=107,050359...≅107,05
verificare
103,597+109,352+107,05=319,999 aproximare de 1/300000 absolut ok
exercitiu absolut nedidactic, nu stiu de unde l-ai luat!!!
