efectuati respectand ordinea operatiilor 1/2+1/3:2/6; 1/2:2/3+3/4:(-5/6); (-5/8):(-10/4)+1/2; 6/4:(-0,625)-0,5:0,(3); 0,5-0,5·1/12; 1/6+1/6:0,25

Answer 1

=1/2+1/3x6/2=1/2+1=3/2
=1/2x3/2+3/4x(-6/5)=3/4-9/10=-3/20
=-5/8x(-4/10)+1/2=1/4+1/2=3/2
=6/4:(-625/1000)-5/10:3/9=6/4x(-1000/625)-5/10x9/3=-12/5-3/2=-39/10
=1/2-1/2x1/12=1/2-1/24=11/24
=1/6+1/6:25/100=1/6+2/3=5/6
