Question

determine as razões entre os fragmentos AB e CD.
a) AB = 24 cm e CD = 36 cm

b)AB = 18 cm e CD = 54 cm

c)AB = 4 m e CD = 60 cm

Answer 1

$a) \frac{ab}{cd } = \frac{24 \div 2}{36 \div 2 } = \frac{12 \div 3}{18 \div 3} = \frac{4 \div 2}{6 \div 2} = \frac{2}{3} (raz.) \\ \\ b) \frac{ab}{cd} = \frac{18 \div 3}{54 \div 3} = \frac{6 \div 6}{18 \div 6} = \frac{1}{3} (rz.)\\ \\ c) \frac{ab}{cd} = \frac{4 \div 2}{60 \div 2} = \frac{2 \div 2}{30 \div 2} = \frac{1}{15} (raz.)$
