Question

Se considera ca A={ -0,5; -0,(3) ;1/3 :1/2 }
Calculati modului sumei elemntelor lui A
Suma modulelor lui A

Answer 1

1/2+1/3+1/3*2.Aducand la acelasi numitor obtinem:
(3+2+6)/6=11/6

Answer 2

modulul sumei elementelor=|-0.5-0.(3)+1/3+1/2|=|-1/2-1/3+1/3+1/2|=0
suma modulelor=|-0.5|+|-0.(3)|+|1/3|+|1/2|=|-1/2|+|-1/3|+1/3+1/2=2/2+2/3=1+0.(6)=1.(6)
