Question

la ex 1 ) amplificati cu 3
la ex 2) simplificati cu 5​

Answer 1

Coroana??

1.

$\frac{1}{2} = \frac{3}{6}$

$\frac{5}{7} = \frac{15}{35}$

$\frac{a}{b} = \frac{3a}{3b}$

$\frac{2x}{5y} = \frac{6x}{15y}$

2.

$\frac{10}{15} = \frac{2}{3}$

$\frac{15}{45} = \frac{3}{9}$

$\frac{5a}{10b} = \frac{a}{2b}$

$\frac{10a + 10b}{25x + 25y} = \frac{2a + 2b}{5x + 5y}$
