Question

classify the following numbers as rational or irrational give reason to support your answer -2

Answer 1

Answer:

-2 is a rational number

Step-by-step explanation:

According to definition a rational number is a number which can be written in the quotient or fraction of two integers in the form of p/q.

-2 can be written as -2/1 hence rational.

And a real that is not rational is called irrational.

Answer 2

Answer:

-2 is a rational number

Step-by-step explanation:

In this question,

Rational numbers are the numbers which can be written in the form of$\mathbf{\frac{p}{q}}$ where q ≠ 0 and {p,q∈Real numbers}. for example $\mathbf{\frac{3}{2}}$

Irrational numbers are the numbers which cannot be written in the form of $\mathbf{\frac{p}{q}}$ where q ≠ 0 and {p,q∈Real numbers}. for example - √3

Therefore, -2 is a rational number as it van be written in the form $\mathbf{\frac{-2}{1}}$.

Therefore, it is written in the $\mathbf{\frac{p}{q}}$form and -1 ≠ 0 and -2 is a real number.
