Answer 2

Hey here is your answer
_______________________

$= \frac{1}{7} \times \frac{49}{1000} + \frac{3}{8} - \frac{7}{20} \\ \\ = \frac{7}{1000} + \frac{3}{8} - \frac{7}{20} \\ \\ = \frac{56 + 3000}{8000} - \frac{7}{20} \\ \\ = \frac{56 + 3000 - 2800}{8000} \\ \\ = \frac{ 3056- 2800}{8000} \\ \\ = \frac{256}{8 \times 1000} \\ \\ = \frac{32}{1000} \\ \\ = 0.032$
