Answer 2

Explicație pas cu pas:

2,4×4,2-3,2:4/5=

2,4×4,2-3,2:0,8=

10,08-4=

6,08

b) 4,5+31/10×2,6=

4,5+3,1×2,6=

4,5+8,06=

12,56

c)

2. a) 25,41-3×(1,2+0,7)=

25,41-3×1,9=

25,41-5,7=

19,71

b) 11,18:[9,4-2×(1,2-0,8)]=

11,18:(9,4-2×0,4)=

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

11,18:8,6=1,3

3. 5,14×{4,1+2×[3-1,4:(2,5-1,7)]}=

5,14×[4,1+2×(3-1,4:0,8)]=

5,14×[4,1+2×(3-1,75)]=

5,14×(4,1+2×1,25)=

5,14×(4,1+2,5)=

5,14×6,6=

33,924

5,14×(4,1+2)×[3-1,4:(2,5-1,7)]=

5,14×6,1×(3-1,4:0,8)=

5,14×6,1×(3-1,75)=

5,14×6,1×1,25=

5,14×7,625=

39,1925

33,925<39,1925

4. (18,16-12,3):2,5=

5,86:2,5=2,344

18,125:(1,3+1,2)×5,4=

18,125:2,5×5,4=

7,25:5,4=

39,15
