Q. Is 22 a rational number?\newlineChoices:\newline(A) yes\newline(B) no
  1. Define Rational Number: Define what a rational number is.\newlineA rational number is a number that can be expressed as the quotient or fraction pq\frac{p}{q} of two integers, where pp is the numerator, qq is the denominator, and q≠0q \neq 0.
  2. Express as Fraction: Express the number 22 as a fraction.\newlineThe number 22 can be written as 21\frac{2}{1}, where 22 is an integer and 11 is an integer.
  3. Check Validity: Check if the fraction 21\frac{2}{1} meets the criteria for a rational number.\newlineSince both 22 and 11 are integers, and 11 is not zero, the fraction 21\frac{2}{1} is a valid representation of a rational number.
  4. Conclude Rational Number: Conclude whether 22 is a rational number based on the previous steps.\newlineSince 22 can be expressed as the fraction 21\frac{2}{1}, it meets the definition of a rational number.
