To divide \( \frac{4}{5} \) by \( 2 \), you can rewrite the division of a fraction by a whole number as follows:
\[ \frac{4}{5} \div 2 = \frac{4}{5} \times \frac{1}{2} \]
Now multiply the fractions:
\[ \frac{4 \times 1}{5 \times 2} = \frac{4}{10} \]
Now, simplify \( \frac{4}{10} \):
\[ \frac{4}{10} = \frac{2}{5} \]
So, \( \frac{4}{5} \div 2 = \frac{2}{5} \).
