Which statement about decimal representation of measurements is correct?

• A. Fractions should be kept as fractions
• B. Fractions should be converted to decimals
• C. Fractions should be converted to percentages
• D. Fractions should be recorded as whole numbers

Answer: (B)

Decimal representation is the standard way to record measurements because it makes arithmetic, comparison, and data handling straightforward. When you convert fractions to decimals, you create a uniform format that calculators, spreadsheets, and reporting tools can work with directly, reducing the chance of errors during calculations or data merging.

For example, a measurement like 3 and 3/8 inches becomes 3.375 inches. You can easily add it to other decimal measurements, such as 4.2 inches, to get 7.575 inches without additional conversions. Keeping values as fractions complicates calculations and mixing formats can lead to mistakes. Percentages express a portion relative to a whole, which is useful in some contexts, but they’re not the usual way to record a raw measurement. Recording a fraction as a whole number would throw away the fractional part and lose precision.
