  1. Set up multiplication: Set up the multiplication of the two fractions.\newline−145×512-\frac{14}{5} \times \frac{51}{2}\newlineShort reasoning: Multiplying two fractions involves multiplying the numerators together and the denominators together.\newlineCalculation: (−14×51)/(5×2)(-14 \times 51) / (5 \times 2)
  2. Perform multiplication: Perform the multiplication for both numerators and denominators.\newline−14×51=−714-14 \times 51 = -714, 5×2=105 \times 2 = 10\newlineShort reasoning: Simple multiplication of integers.\newlineCalculation: −714/10-714 / 10
  3. Simplify fraction: Simplify the fraction to get the final answer.\newline−714/10=−71.4-714 / 10 = -71.4\newlineShort reasoning: Dividing −714-714 by 1010 gives the decimal −71.4-71.4.\newlineCalculation: Final answer is −71.4-71.4
