Write as a fraction in lowest terms. 0.2 \( 0.2=\square \) (Type an integer or a fraction. Simplify your answer.)

To express 0.2 as a fraction, you can think of it as \(\frac{2}{10}\) because 0.2 is the same as 2 tenths. Now, simplify \(\frac{2}{10}\) by dividing both the numerator and the denominator by their greatest common divisor, which is 2. This gives: \(\frac{2 \div 2}{10 \div 2} = \frac{1}{5}\) So, \(0.2 = \frac{1}{5}\) in lowest terms.
