Answer 1

1. -4/9 -5/18(amplificam cu 2 prima) = -13/18

2. -7/3-10/15=-7/3 -2/3=-9/3=-3

3. 3+3+1/7=6+1/7=6·1/7=43/7

4. 5/4-17/6=-19/12=-1· 7/12

5. (se simplifica 3 cu 3 si 4 cu 2) =3/4 -1/2=1/4

6. 4/3·1/3+3/2=4/9+3/2=35/18=1× 17/18

7. 2/3+1/2·1/3=2/3+1/6=5/6

8.  (1/5+1/18)·3=23/90 · 3=23/30

9. 3/5+1/2+1/2=8/5
