Compare \(\frac{2}{5}\) and \(\frac{1}{10}\).

Find a common denominator.

The least common denominator (LCD) of 5 and 10 is 10.

Convert \(\frac{2}{5}\) to a fraction with denominator 10.

Multiply the numerator and denominator of \(\frac{2}{5}\) by 2:
\[ \frac{2}{5} = \frac{2 \times 2}{5 \times 2} = \frac{4}{10}. \]
