Answer 2

Step-by-step explanation:

$\frac{3}{49} \div \frac{1}{7} + ( \frac{1}{5} + \frac{7}{10} ) \times \frac{4}{21}$

$\frac{3}{49} \div \frac{1}{7} + ( \frac{1}{5} \times 2 + \frac{7}{10} ) \times \frac{4}{21}$

$\frac{3}{49} \div \frac{1}{7} + ( \frac{2}{10} + \frac{7}{10} ) \times \frac{4}{21}$

$\frac{3}{49} \div \frac{1}{7} + \frac{9}{10} \times \frac{4}{21}$

$\frac{3}{49} \times \frac{7}{1} + \frac{9}{10} \times \frac{4}{21}$

$\frac{21}{49} + \frac{36}{210}$

$(\frac{21}{49} \times 30)+ (\frac{36}{210} \times 7)$

$\frac{630 + 252}{1470}$

$\frac{882}{1470}$

$\frac{147}{245}$
