Question

List all rational numbersLet A={0,0.2222,√3,2,-2/3,-7,√7}

Answer 1

[0,0.2222,2,-2/3,-7]

Step-by-step explanation:

A rational number is a number that can be expressed as the quotient or fraction p/q of two integers, a numerator p and a non-zero denominator q.

$0$ can be written as $\frac{0}{1}$,so it is a rational number.

$0.2222$ can be written as $\frac{2222}{10000}$,so it is a rational number.

$\sqrt{3}$ cannot be written as a fraction,so it is not a rational number.

$2$ can be written as $\frac{2}{1}$,so it is a rational number.

$\frac{-2}{3}$ can be written as $\frac{-2}{3}$,so it is a rational number.

$-7$ can be written as $\frac{-7}{1}$,so it is a rational number.

$\sqrt{7}$ cannot be written as a fraction,so it is not a rational number.
