Question

simplifique as seguintes frações fazendo divisões sucessivas:

•180/360

•40/84

•120/70

•63/90

Answer 1

vamos lá...

$\frac{180:2}{360:2} = \frac{90:2}{180:2} = \frac{45 :3}{90:3} = \frac{15:3}{30:3} = \frac{5:5}{10:5} =\fbox{ \frac{1}{2} } \\ \\ \frac{40:2}{84:2} = \frac{20:2}{42:2} = \fbox{ \frac{10}{21} } \\ \\ \frac{120:2}{70:2} = \frac{60:5}{35:5} =\fbox{ \frac{12}{7} } \\ \\ \frac{63:3}{90:3} = \frac{21:3}{30:3} =\fbox{ \frac{7}{10} }$

Answer 2

•180/360=180/4*180=1/4

•40/84 =10/21

•120/70=12/7

•63/90=31/30
