DAU COROANA!!!


Răspuns :

A)

[tex] \frac{ - 6}{ - 9} = \frac{6}{9} = \frac{2}{3} [/tex]

(am simplificat cu 3)

[tex] \frac{18}{27} = \frac{2}{3} [/tex]

(am simplificat cu 9)

[tex] \frac{2}{3} = \frac{ - 6}{ - 9} = \frac{18}{27} [/tex]

B)

[tex] - \frac{24}{40} = - \frac{3}{5} [/tex]

(am simplificat cu 8)

[tex] - \frac{21}{35} = - \frac{3}{5} [/tex]

(am simplificat cu 7)

[tex] - \frac{3}{5} = - \frac{24}{40} = - \frac{21}{35} [/tex]
