Question

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

$(a)\frac{AB}{BC}=\frac{5}{15}\div5= \frac{1}{3}cm\\\\(b)\frac{CD}{DE}=\frac{4}{10}\div2=\frac{2}{5}cm\\\\(c)\frac{AC}{CD}=\frac{20}{4}=5cm\\\\(d)\frac{EF}{FG}=\frac{8}{16}\div8=\frac{1}{2}m=50cm\\\\(e)\frac{EG}{CD}=\frac{24}{4}=6m\\\\(f)\frac{FG}{AC}=\frac{16}{20}\div4=\frac{4}{5}cm$

Espero ter ajudado.
Bons estudos! :)
