Answer 1

Explicação passo-a-passo:

a) $\dfrac{90}{40}=\dfrac{90\div2}{40\div2}=\dfrac{45}{20}=\dfrac{45\div5}{20\div5}=\dfrac{9}{4}$

b) $\dfrac{12}{21}=\dfrac{12\div3}{21\div3}=\dfrac{4}{7}$

c)

$\dfrac{8}{24}=\dfrac{8\div2}{24\div2}=\dfrac{4}{12}=\dfrac{4\div2}{12\div2}=\dfrac{2}{6}=\dfrac{2\div2}{6\div2}=\dfrac{1}{3}$
