Question

2/5*4/7+3/7-3/5*2/5 plz I need it fast

Answer 1

$\frac{2}{5} \times \frac{4}{7} + \frac{3}{7} - \frac{3}{5} \times \frac{2}{5} \\ \\ = \frac{8}{35} + \frac{3}{7} - \frac{6}{25} \\ \\ = \frac{8 \times 5 + 3 \times 25 - 6 \times 7}{175} \\ \\ = \frac{40 + 75 - 42}{175} \\ \\ = \frac{115 - 42}{175} \\ \\ = \frac{73}{175}$

If any doubt, please ask :)
