volume_mute
The rule states: The quotient of two integers with different (unlike) signs is negative.
Select all expressions that have a negative quotient based on this definition.
Correct Answer
(1) \(-14 \div 7\)
(2) \(30 \div (-5)\)
Explanation
Unlike signs (one positive, one negative) → negative quotient:
- \(-14 \div 7 = -2\) ✓ (negative ÷ positive)
- \(30 \div (-5) = -6\) ✓ (positive ÷ negative)
Like signs → positive: \(-14 \div (-7) = 2\) and \(-30 \div (-5) = 6\).
