Question

Identify the two rational numbers. A) √2 B) 1.01 C) 1.010010001... C) -2/5

Answer 1

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.
