Answer 1

Răspuns:

4. a) $\frac{1*1}{4*5} = \frac{1}{20}$

b) $\frac{3*2}{7*11} =\frac{6}{77}$

c) $\frac{1*5}{8*2}$= $\frac{5}{16}$  ( am simplificat 6 cu 3)

d) $\frac{5*1}{3*4} = \frac{5}{12}$  ( am simplificat 9 cu 3)

e) $\frac{1*1}{3*2} = \frac{1}{6}$  ( am simplificat 14 cu 7 si 15 cu 5)

f) $\frac{1*1}{2*4} = \frac{1}{8}$ ( am simplificat 20 cu 5 si 6 cu 3)

5. $\frac{1}{3} *\frac{3}{4}$ = $\frac{1}{4}$

$\frac{1}{4} * \frac{4}{5}$= $\frac{1}{5}$

$\frac{1}{5} *\frac{5}{6} =\frac{1}{6}$  

$\frac{1}{6} *\frac{6}{7} =\frac{1}{7}$
