a)Pentru ca [tex] \frac{2}{2} =1[/tex], iar [tex] \frac{2}{4} = \frac{1}{2} [/tex],
fractiile nu sunt [tex] \frac{2}{2} [/tex][tex] \neq [/tex][tex] \frac{2}{4} [/tex]
b)Pentru a afla daca sunt egale le amplificam:
[tex] \frac{5}{10} ^{7} = \frac{35}{70} [/tex]
[tex] \frac{5}{7} ^{10} = \frac{50}{70} [/tex]
Prin urmare [tex] \frac{35}{70} \neq \frac{50}{70} [/tex], de asemenea si [tex] \frac{5}{10} \neq \frac{5}{7} [/tex]
c)pentru ca [tex] \frac{3}{3}=1 [/tex], de asemenea si [tex] \frac{5}{5} =1[/tex]
putem spune ca [tex] \frac{3}{3}= \frac{5}{5} [/tex]
