To express the decimal 0.4 as a fraction, you can follow these steps:
1. Recognize that 0.4 is the same as \( \frac{4}{10} \) since there is one digit after the decimal point.
2. Simplify the fraction \( \frac{4}{10} \) by dividing both the numerator and denominator by their greatest common divisor, which is 2:
\[
\frac{4 \div 2}{10 \div 2} = \frac{2}{5}
\]
Therefore, 0.4 as a simplified fraction is:
\[
\frac{2}{5}
\]
