To find a fraction equivalent to \( \frac{2}{5} \), you can multiply the numerator and the denominator by the same non-zero integer.
For example, if we multiply both the numerator and denominator by 2:
\[ \frac{2 \times 2}{5 \times 2} = \frac{4}{10} \]
So, \( \frac{4}{10} \) is an equivalent fraction to \( \frac{2}{5} \).
You can also multiply by other numbers. For example, multiply by 3:
\[ \frac{2 \times 3}{5 \times 3} = \frac{6}{15} \]
So, \( \frac{6}{15} \) is also an equivalent fraction to \( \frac{2}{5} \).
In general, any fraction of the form \( \frac{2n}{5n} \), where \( n \) is a non-zero integer, will be equivalent to \( \frac{2}{5} \).
