You asked:

Evaluate the expression: \(\frac{2}{5} \cdot \frac{-3}{7} - \frac{\frac{3}{7} \cdot 3}{5}\)

MathBot Answer:

\[\frac{2}{5} \cdot \frac{-3}{7} - \frac{\frac{3}{7} \cdot 3}{5} = - \frac{3}{7} = -0.\overline{428571}\]

\[\begin{aligned}\frac{2}{5} \cdot \frac{-3}{7} - \frac{\frac{3}{7} \cdot 3}{5}& = \frac{2}{5} \cdot - \frac{3}{7} - \frac{3}{7} \cdot \frac{3}{5}\\& = - \frac{6}{35} - \frac{3}{7} \cdot \frac{3}{5}\\& = - \frac{6}{35} - \frac{9}{35}\\& = - \frac{3}{7}\end{aligned}\]
