Question

1 și 2
Va rog ajutatima urgent

Answer 1

ex 1)
$a) \frac{14}{4} = \frac{7}{2} \\ \\ b) \frac{4}{6} = \frac{10 }{15} \\ \\ c) \frac{6}{15} = \frac{10}{25} \\ \\ d) \frac{10}{6} = \frac{15}{9}$


ex 2)

$a) \frac{x + 1}{5} = \frac{4}{2} \\ \frac{10}{5} = \frac{4}{2} = > x = 9 \\ \\ \\ b) \frac{4}{x + 3} = \frac{6}{9} \\ \frac{4}{6} = \frac{6}{9} = > x = 3$
$c) \frac{x + 2}{x + 5} = \frac{5}{8} \\ \frac{5}{8} = \frac{5}{8} = > x = 3$

Sper că te-am ajutat !
