Answer 1

Explicação passo-a-passo:

• $\sf \dfrac{42}{105}=\dfrac{42\div3}{105\div3}=\dfrac{14}{35}$

$\sf \dfrac{42}{105}=\dfrac{14\div7}{35\div7}=\red{\dfrac{2}{5}}$

• $\sf \dfrac{36}{90}=\dfrac{36\div2}{90\div2}=\dfrac{18}{45}$

$\sf \dfrac{36}{90}=\dfrac{18\div3}{45\div3}=\dfrac{6}{15}$

$\sf \dfrac{36}{90}=\dfrac{6\div3}{15\div3}=\red{\dfrac{2}{5}}$

São equivalentes
