Question

using appropriate properties, find –1/3×2/7 – 1/42 + 2/3 × 2/7​

Answer 1

Answer:

★ $\dfrac{- 1}{3} \times \dfrac{2}{7} - \dfrac{1}{42} + \dfrac{2}{3} \times \dfrac{2}{7}$

$\implies\dfrac{- 2}{21} - \dfrac{1}{42} + \dfrac{4}{21}$

$\implies\dfrac{- 4 - 1 + 8}{42}$

$\implies\dfrac{- 4 + 7}{42}$

$\implies\dfrac{\: \: \: \: \: \: \: \cancel{3}^{\: 1}}{\: \: \: \: \: \: \:\cancel{42}^{\: 14}}$

$\implies\dfrac{1}{14}$

$\therefore\sf\: The\: answer\: of\: this\: question\: is\: \dfrac{1}{14}$
