Correct Answer: 300

Explanation

Concept & Logic Finding "how many" of a specific fractional part exists inside a total amount is a straightforward division problem. The logic translates directly to dividing the total value by the size of the part: $$\text{Total} \div \text{Part}$$. Step-by-Step Solution * Identify the total amount: $$37\frac{1}{2}$$ * Identify the size of the part: $$\frac{1}{8}$$ * Convert the mixed fraction into an improper fraction for calculation: $$37\frac{1}{2} = \frac{37 \times 2 + 1}{2} = \frac{75}{2}$$ * Set up the division equation: $$\frac{75}{2} \div \frac{1}{8}$$ * To divide by a fraction, multiply by its reciprocal: $$\frac{75}{2} \times \frac{8}{1}$$ * Simplify the expression by cancelling the common factor of 2 in the denominator and 8 in the numerator: $$75 \times 4 = 300$$ Exam Strategy & Shortcut Whenever asked "How many $x$ are in $y$?", immediately calculate $y \times \frac{1}{x}$. Recognizing that dividing by $\frac{1}{8}$ is identical to multiplying by 8 allows you to solve this mentally: $37.5 \times 8 = 300$. Common Pitfall A common mistake is reversing the division order (e.g., dividing $\frac{1}{8}$ by $37\frac{1}{2}$), which yields a tiny fraction instead of an integer count. Always ensure the "Total" is the dividend (the number being divided). Final Answer Therefore, the correct answer is **300**.
