Answer 1

Explicação passo-a-passo:

a)

$\sf \dfrac{2}{3}\div\dfrac{5}{2}\rightarrow\dfrac{4}{6}\div\dfrac{15}{6}=\dfrac{(4\div15)}{1}=\dfrac{4}{15}$

b)

$\sf \dfrac{13}{9}\div\dfrac{169}{3}\rightarrow\dfrac{13}{9}\div\dfrac{507}{9}=\dfrac{(13\div507)}{1}=\dfrac{1}{39}$

c)

$\sf \dfrac{2}{3}\div\dfrac{1}{6}\rightarrow\dfrac{4}{6}\div\dfrac{1}{6}=\dfrac{(4\div1)}{1}=4$
