Answer 2

$Let \: a \: number \: \blue {x} \: should \:be \\added \:to\: 5 \frac{1}{5} \: to \:get \: 7 \frac{3}{7}$

$\blue {x} + 5 \frac{1}{5} = 7 \frac{3}{7}$

$\implies \blue {x} + \frac{26}{5} = \frac{52}{7}$

$\implies \blue {x} = \frac{52}{7} - \frac{26}{5}$

$\implies \blue {x} = \frac{260 - 182}{35}$

$\implies \blue {x} = \frac{78}{35}$

Therefore.,

$\blue {\frac{78}{35}} \: should \:be \:added\\ \:to\: 5 \frac{1}{5} \: to \:get \: 7 \frac{3}{7}$
