Question

2-Determine a razão entre os segmentos a)- AB = 5 cm e BC = 15 cm b)- CD = 4 cm e DE = 10 cm c)- AC = 20 cm e CD = 4 cm d)- EF = 8 m e FG = 16 m e)- EG = 24 m e CD = 4 m f)- FG =16 cm e AC = 20 cm

Answer 1

vamos lá...

razão

$a) \\ ~~ \frac{AB}{BC} = \frac{5}{15} ~~simplificando~~ \frac{5:5}{15:5} = \frac{1}{3} \\ \\ b) \\ ~~ \frac{CD}{DE} = \frac{4}{10} = \frac{4:2}{10:2} = \frac{2}{5} \\ \\ c) \\ ~~ \frac{AC}{CD} = \frac{20}{4} = \frac{20:4}{4:4} = \frac{5}{1} \\ \\ d) \\ ~~ \frac{EF}{FG} = \frac{8}{16} = \frac{8:8}{16:8} = \frac{1}{2} \\ \\ e) \\ ~~ \frac{EG}{CD} = \frac{24}{4} = \frac{24:4}{4:4} = \frac{6}{1} \\ \\ f) \\ ~~ \frac{FG}{AC} = \frac{16}{20} = \frac{16:4}{20:4} = \frac{4}{5}$
