Q:

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

Accepted Solution

A:
[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.[tex]0[/tex] can be written as [tex]\frac{0}{1}[/tex],so it is a rational number.[tex]0.2222[/tex] can be written as [tex]\frac{2222}{10000}[/tex],so it is a rational number.[tex]\sqrt{3}[/tex] cannot be written as a fraction,so it is not a rational number.[tex]2[/tex] can be written as [tex]\frac{2}{1}[/tex],so it is a rational number.[tex]\frac{-2}{3}[/tex] can be written as [tex]\frac{-2}{3}[/tex],so it is a rational number.[tex]-7[/tex] can be written as [tex]\frac{-7}{1}[/tex],so it is a rational number.[tex]\sqrt{7}[/tex] cannot be written as a fraction,so it is not a rational number.
