Question

simplifique as frações, através das divisões sucessivas, até torná-las irredutíveis:

A) 4/12

B)20/100

C)35/80

D) 18/36

Answer 1

$A) \\ \frac{4:2}{12:2} = \frac{2:2}{6:2} = \frac{1}{3} \\ \\ B) \\ \frac{20:2}{100:2}= \frac{10:2}{50:2} = \frac{5:5}{25:5} = \frac{1}{5} \\ \\ C) \\ \frac{35:5}{80:5} = \frac{7}{16} \\ \\ E) \\ \frac{18:2}{36:2} = \frac{9:3}{18:3} = \frac{3:3}{6:3} = \frac{1}{2}$
