$\implies {\pink {\boxed {\boxed {\purple {\sf { \: x = \frac{2}{7}}}}}}}$

$\large\mathfrak{{\pmb{\underline{\red{Step-by-step\:explanation}}{\red{:}}}}}$

Let be the unknown number.

As per the question, we have

$\: ( \frac{3}{7} \times \frac{2}{5} ) - x = \frac{ - 4}{35}$

➺ $\: \frac{6}{35} - x = \frac{ - 4}{35}$

➺ $\: - x = \frac{ - 4}{35} - \frac{6}{35}$

➺ $\: - x = \frac{ - 4 - 6}{35}$

➺ $\: - x = \frac{ - 10}{35}$

➺ $\: x = \frac{2}{7}$

Therefore, $\frac{2}{7}$ should be subtracted from the product of $\frac{3}{7}$ and $\frac{2}{5}$ to get $\frac{ - 4}{35}$ .

$\large\mathfrak{{\pmb{\underline{\orange{To\:verify}}{\orange{:}}}}}$

$\: ( \frac{3}{7} \times \frac{2}{5} ) - x = \frac{ - 4}{35}$

➼ $\: ( \frac{6}{35} ) - \frac{2}{7} = \frac{ - 4}{35}$

➼ $\: \frac{6}{35} - \frac{2 \times 5}{7 \times 5} = \frac{ - 4}{35}$

➼ $\: \frac{6 - 10}{35} = \frac{ - 4}{35}$

➼ $\: \frac{ - 4}{35} = \frac{ - 4}{35}$

➼ $\: L.H.S.=R. H. S$

$\sf\purple{Hence\:verified. }$
