Answer 1

Răspuns:

Explicație pas cu pas:

$a) \frac{30}{12} = \frac{30:2}{12:2} = \frac{15:3}{6:3} = \frac{5}{2}$

$b) \frac{28}{42} = \frac{28:7}{42:7} = \frac{4:2}{6:2} = \frac{2}{3}$

$c) \frac{45}{27} = \frac{45:9}{27:9} = \frac{5}{3}$

$d) \frac{75}{25} = \frac{75:25}{25:25} = \frac{3}{1}$

$e) \frac{60}{84} = \frac{60:4}{84:4} = \frac{15:3}{21:3} = \frac{5}{7}$

$f) \frac{256}{288} = \frac{256:4}{288:4} = \frac{64:8}{72:8} = \frac{8}{9}$
