Hello Dear User__________

Here is Your Answer...!!

Step by step solution:

$Let \ the \ number \ be \ x\\\\(\frac{3}{7}\times \frac{2}{5})-(x)=(-\frac{4}{35})\\ \\\frac{6}{35}-x=(-\frac{4}{35})\\\\x=\frac{6}{35} +\frac{4}{35}\\\\x=\frac{10}{35}$

$Verification\\\\(\frac{3}{7} \times \frac{2}{5})-(\frac{10}{35})=(-\frac{4}{23}\\\\\frac{6}{35}- \frac{10}{35}=- \frac{4}{35}\\\\- \frac{4}{35}=- \frac{4}{35}\\\\Hence \ verified$

Hope it is clear to you.
