Answer 2

$\frac{2}{5} \times ( \frac{1}{7} - \frac{1}{12}) \times \frac{7}{5} \\ = > \frac{2}{5} \times \frac{5}{84} \times \frac{7}{5} \\ = \frac{1}{3}$

$here \: 84 \: is \: cut \: by \: 7 \: and \: 5 \: is \: cut \: by \: 5 \: and \: the \: result \: of \: cutting \: 84 \: by \: 7 \: is \: 12 \: and \: it \: is \: cut \: by \: 2$
