Answer 1

Explicação passo-a-passo:

a) $\dfrac{6}{x}=\dfrac{4}{2}$

$\dfrac{6}{x}=2$

$2x=6$

$x=\dfrac{6}{2}$

$\boxed{x=3}$

$\dfrac{2}{y}=\dfrac{3}{5}$

$3y=10$

$\boxed{y=\dfrac{10}{3}}$

b) $\dfrac{x}{2}=\dfrac{6}{3}$

$\dfrac{x}{2}=2$

$\boxed{x=4}$

$\dfrac{y}{3}=\dfrac{4}{2}$

$\dfrac{y}{3}=2$

$\boxed{y=6}$

c) $\dfrac{x}{3}=\dfrac{4}{6}$

$6x=12$

$x=\dfrac{12}{6}$

$\boxed{x=2}$

$\dfrac{10}{3}=\dfrac{y}{6}$

$3y=60$

$y=\dfrac{60}{3}$

$\boxed{y=20}$

d) $\dfrac{x}{10}=\dfrac{2}{4}$

$4x=20$

$x=\dfrac{20}{4}$

$\boxed{x=5}$

$\dfrac{y}{12}=\dfrac{5}{10}$

$10y=60$

$y=\dfrac{60}{10}$

$\boxed{y=6}$
