Answer 2

Explicação passo-a-passo:

Resolução!!!

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)

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