Explicación paso a paso:

$\frac{1}{3}+\frac{2}{5}-\frac{2}{3}\\\\\\\frac{1-2}{3}+\frac{2}{5}\\\\\\\frac{-1}{3}+\frac{2}{5}\\\\\\-\frac{1}{3}+\frac{2}{5}\\\\\\-\frac{5}{15}+\frac{6}{15}\\\\\\\frac{-5+6}{15}\\\\\\\frac{1}{15}$

No te olvides <3

$\frac{a}{c}\pm \frac{b}{c}=\frac{a\pm \:b}{c}\\\\\\\frac{a}{c}+\frac{b}{c}=\frac{a+b}{c}$
