Answer 1

$\dfrac{2}{a} = \dfrac{6}{b} = \dfrac{12}{c} = \dfrac{2+6+12}{a+b+c} = \dfrac{20}{1000} = \dfrac{1}{50}$

$\dfrac{2}{a} = \dfrac{1}{50} \iff a = 2 \cdot 50 \implies a = 100$

$\dfrac{6}{b} = \dfrac{1}{50} \iff b = 6 \cdot 50 \implies b = 300$

$\dfrac{12}{c} = \dfrac{1}{50} \iff c = 12 \cdot 50 \implies c = 600$
