Answer 2

$\huge \underline\green{ answer : - }$

$\huge \boxed {\red{ \frac{74}{35} }}$

$\huge \: steps : - -$

$\huge \purple{ \frac{7}{5} + \frac{5}{7} }$

$\huge \boxed{lcm = 35}$

$\huge \frac{7}{5} \times \frac{7}{7} + \frac{5}{7} \times \frac{5}{5}$

$\huge \: \frac{49}{35} + \frac{25}{35}$

$\huge \: \frac{49 + 25}{35}$

$\huge= \frac{74}{35}$

_________________________

$\huge \boxed{another \: method}$

$\huge \blue{cross \: multiplication}$

$\huge= ( \frac{7 \times 7 +5 \times 5 }{7 \times 5} )$

$\huge = \frac{49 + 25}{35}$

$\huge = \frac{74}{34}$

$\huge =2.1142857...$
