Answer:
[tex]\Huge \boxed{\mathrm{ Rational }}[/tex]
Step-by-step explanation:
Rational numbers can be expressed as fractions with whole numbers as the numerator and the denominator.
[tex]\displaystyle \frac{0.4}{0.8}[/tex]
Multiply both the numerator and the denominator by 10.
[tex]\displaystyle \frac{4}{8} =\frac{1}{2}[/tex]
The result is a simplified fraction with both the numerator and the denominator being whole numbers. The result is rational.
