To convert $0.2$ to a fraction:

1. Recognize that $0.2$ is in the tenths place, so it can be written as: $0.2 = \frac{2}{10}$

2. Simplify the fraction by dividing both the numerator and the denominator by their greatest common divisor (GCD), which is 2: $\frac{2}{10} = \frac{2 \div 2}{10 \div 2} = \frac{1}{5}$

So, $0.2$ as a fraction is $\frac{1}{5}$.
