How do you write 0.2 in the form ab using integers to show what it is a rational number?

To express 0.2 in the form of ( \frac{a}{b} ), where ( a ) and ( b ) are integers, you can write 0.2 as ( \frac{2}{10} ). This fraction can be simplified to ( \frac{1}{5} ) by dividing both the numerator and denominator by 2. Since both the numerator and denominator are integers, 0.2 is confirmed as a rational number.
