2\times \frac{1}{5}m+2\left(-\frac{2}{5}\right)+\frac{3}{5}
Use the distributive property to multiply 2 by \frac{1}{5}m-\frac{2}{5}.
\frac{2}{5}m+2\left(-\frac{2}{5}\right)+\frac{3}{5}
Multiply 2 and \frac{1}{5} to get \frac{2}{5}.
\frac{2}{5}m+\frac{2\left(-2\right)}{5}+\frac{3}{5}
Express 2\left(-\frac{2}{5}\right) as a single fraction.
\frac{2}{5}m+\frac{-4}{5}+\frac{3}{5}
Multiply 2 and -2 to get -4.
\frac{2}{5}m-\frac{4}{5}+\frac{3}{5}
Fraction \frac{-4}{5} can be rewritten as -\frac{4}{5} by extracting the negative sign.
\frac{2}{5}m+\frac{-4+3}{5}
Since -\frac{4}{5} and \frac{3}{5} have the same denominator, add them by adding their numerators.
\frac{2}{5}m-\frac{1}{5}
Add -4 and 3 to get -1.
