Q. Is −7-7 an irrational number?\newlineChoices:\newline(A) yes\newline(B) no
  1. Define irrational number: Step 11: Define an irrational number.\newlineAn irrational number cannot be expressed as a simple fraction, meaning it cannot be written as a ratio of two integers. Irrational numbers have non-terminating, non-repeating decimal expansions.
  2. Analyze number −7-7: Step 22: Analyze the number −7-7.−7-7 is an integer, which means it can be expressed as −7/1-7/1, where both −7-7 and 11 are integers.
  3. Determine if −7-7 is irrational: Step 33: Determine if −7-7 fits the definition of an irrational number.\newlineSince −7-7 can be expressed as a ratio of two integers (−7-7 and 11), it is not an irrational number; it is a rational number.
