To express 0.8 as a rational number, you can write it as a fraction.
Since 0.8 is equivalent to \( \frac{8}{10} \), you can simplify this fraction by dividing both the numerator and the denominator by their greatest common divisor, which is 2:
\[
\frac{8 \div 2}{10 \div 2} = \frac{4}{5}
\]
Thus, 0.8 as a rational number is \( \frac{4}{5} \).
