3. a) 1 intreg si 2/9×314/100= 11/9×314/100= 3454/900 = 1727/450

b) -56/10×6/9=-336/90=-112/30= -56/15

c) -11/10 ×(-2 intregi si 3/9)=11/10×21/9=231/90=77/30

d) 3 intregi si 2/9 ×(-1 intreg si 43-4/90)=

29/9×(-129/90)= - 3741/810=-1247/270

5. A=9/7:3=9/7×1/3=3/7

B=9:(-3/7)=9×(-7/3)=-21

C=-28/27: (-12/9)=-28/27×(-9/12)=28/36=14/18=7/9

D=-34/15:16/5=-34/15×5/16=-34/48=-17/24

E= -62/3: 62/4= -62/3×4/62=4/3

F= 14/10:10/21=14/10×21/10=294/100=147/50

G=17/15 :(-un intreg si 13-1/90)=17/15:(-112/90) =17/15 × ×90/112=102/112=51/56
