\[1)\ \left| \frac{1}{3} - 0,3 \right| = \left| \frac{1}{3} - \frac{3}{10} \right| =\]
\[= \left| \frac{10}{30} - \frac{9}{30} \right| = \frac{1}{30}\]
\[2)\ \left| \frac{1}{3} - 0,4 \right| = \left| \frac{1}{3} - \frac{4}{10} \right| =\]
\[= \left| \frac{10}{30} - \frac{12}{30} \right| = \left| - \frac{2}{30} \right| = \frac{1}{15}\]
\[3)\ \left| \frac{1}{3} - 0,33 \right| = \left| \frac{1}{3} - \frac{33}{100} \right| =\]
\[= \left| \frac{100}{300} - \frac{99}{300} \right| = \frac{1}{300}\]
