Question

Verificati daca fractiile urmatoare reprezinta acelasi numar rational:
A) 2/3; -6 /-9; 18/27
B) -3/5; 24/-40; - 21/35
DAU COROANA!!!

Answer 1

A)

$\frac{ - 6}{ - 9} = \frac{6}{9} = \frac{2}{3}$

(am simplificat cu 3)

$\frac{18}{27} = \frac{2}{3}$

(am simplificat cu 9)

$\frac{2}{3} = \frac{ - 6}{ - 9} = \frac{18}{27}$

B)

$- \frac{24}{40} = - \frac{3}{5}$

(am simplificat cu 8)

$- \frac{21}{35} = - \frac{3}{5}$

(am simplificat cu 7)

$- \frac{3}{5} = - \frac{24}{40} = - \frac{21}{35}$
