2. "Seven-eighths of a number is 63.

To find the original number, you can set up the equation: \( \frac{7}{8} x = 63 \). Solving for \( x \) means multiplying both sides by \( \frac{8}{7} \), resulting in \( x = 63 \times \frac{8}{7} = 72 \). So, the original number is 72! If you ever find yourself stuck on similar problems, remember to convert fractions to their decimal equivalents when possible, as this can make calculations easier! A common mistake is forgetting to multiply or divide by the correct factor when rearranging equations, so double-check those steps!
