Course Activity: Relationships Between <5 of 1 C? Question Mark says that the number 2 is a rational number because he can write it as the fraction 2. Is Mark correct? Why or why not?

a) Yes, because 2 is a whole number.
b) No, because 2 is an irrational number.

Answer 1

Mark is not correct. 2 is a rational number because it can be written as a fraction.

Step-by-step explanation:

No, Mark is not correct. A rational number is a number that can be expressed as a fraction, where both the numerator and denominator are integers and the denominator is not zero. In the case of 2, it can be written as the fraction 2/1, where both the numerator and denominator are integers. Therefore, 2 is a rational number.

Example: 2 (whole number) can be written as 2/1 (fraction).

Rational numbers include whole numbers, integers, and fractions.
