Q. Multiply. \newline12×−25=\frac{1}{2} \times -\frac{2}{5} = _____
  1. Identify numbers: Identify the numbers to multiply.\newlineWe have 12\frac{1}{2} and −25-\frac{2}{5}. We need to multiply these fractions together.\newlineCalculation: (12)×(−25)(\frac{1}{2}) \times (-\frac{2}{5})
  2. Perform calculation: Multiply the numerators and then the denominators.\newlineNumerator: 1×−2=−21 \times -2 = -2\newlineDenominator: 2×5=102 \times 5 = 10\newlineSo, the product is −210\frac{-2}{10}.
  3. Multiply numerators and denominators: Simplify the fraction.\newline−210-\frac{2}{10} can be simplified by dividing both the numerator and the denominator by 22.\newlineCalculation: (−2÷2)/(10÷2)=−15(-2 \div 2) / (10 \div 2) = -\frac{1}{5}
