̃ 2 - Simplifique as frações abaixo
​

Answer 1

Resposta:

Olá,

$\mathbf{a) \: \dfrac{18}{24} = \dfrac{18 \div 2}{24 \div 2} = \dfrac{9 \div 3}{12 \div 3} = \dfrac{3}{4}}$

$\mathbf{b) \: \dfrac{24}{32} = \dfrac{24 \div 2}{32 \div 2} = \dfrac{12 \div 2}{16 \div 2} = \dfrac{6 \div 2}{8 \div 2} = \dfrac{3}{4}}$

$\mathbf{c) \: \dfrac{4}{20} = \dfrac{4 \div 2}{20 \div 2} = \dfrac{2 \div 2}{10 \div 2} = \dfrac{1}{5} }$

$\mathbf{d) \: \dfrac{45}{63} = \dfrac{45 \div 9}{63 \div 9} = \dfrac{5}{7}}$

$\mathbf{e) \: \dfrac{75}{30} = \dfrac{75 \div 5}{30 \div 5} = \dfrac{15}{6}}$

$\mathbf{f) \: \dfrac{42}{105} = \dfrac{42 \div 21}{105 \div 21} = \dfrac{2}{5}}$

Answer 2

Resposta:

Veja Abaixo

Explicação passo-a-passo:

A)

$\dfrac{18}{24} = \dfrac{18 {}^{ \div 6} }{24 {}^{ \div 6} } = > \dfrac{3}{4}$

B)

$\dfrac{24}{34} = \dfrac{24 {}^{ \div 8} }{32 {}^{ \div 8} } = > \dfrac{3}{4}$

C)

$\dfrac{4}{20} = \dfrac{4 {}^{ \div 4} }{20 {}^{ \div 4} } = > \dfrac{1}{5}$

D)

$\dfrac{45}{63} = \dfrac{45 {}^{ \div 9} }{63 {}^{ \div 9} } = > \dfrac{5}{7}$

E)

$\dfrac{75}{30} = \dfrac{75 {}^{ \div 15} }{30 {}^{ \div 15} } = > \dfrac{5}{2}$

F)

$\dfrac{42}{105} = \dfrac{42 {}^{ \div 21} }{105 {}^{ \div 21} } = > \dfrac{2}{5}$
