Answer 1

Răspuns:

a) 19,71

b) 1,3

Explicație pas cu pas:

a) 25, 41 - 3×(1, 2 + 0, 7) =

= 25,41 - 3 x 1,9 =

= 25,41 - 5,7 =

= 19,71

b) 11, 18 : [9, 4 - 2×(1, 2 - 0, 8)]​ =

= 11,18 : (9,4 - 2 x 0,4) =

= 11,18 : (9,4 - 0,8) =

= 11,18 : 8,6 =

= 1,3

Answer 2

Răspuns:

a)25,41-3×(1,2+0,7)=1,2+0,7=1,9×3=5,7=25,41-5,7=19,71

b)11,18:[9,4-2×(1,2-0,8)]=1,2-0,8=0,4×2=0,8=9,4-0,8=8,6=11,18:8 6=1,3
