Tucker Kim · Answer 2

Rational numbers can be written as fractions. A is an irrational number because it has infinite digits that cannot be written as a fraction. B is a rational number because it has finite digits. C is an irrational number because it has infinite digits that cannot be written as a fraction. D is rational because it is a fraction.

So - 2/5 and 1.01 are rational.
