If your computed answer is a fraction that is too long, what should you do?

• A. Write the decimal equivalent.
• B. Keep the fraction as is.
• C. Convert to a mixed number.
• D. Round to the nearest whole number.

Answer: (A)

When a computed result yields a long fraction, write its decimal equivalent. Decimals are compact, easy to read, and they line up with how answers are typically given on the PSAT. If a problem specifies a precision, you can round to that many decimal places. Rounding to a whole number would sacrifice a lot of detail, and keeping the result as a fraction—even as a mixed number—can be awkward to scan and compare with other answers. A decimal gives a practical, usable approximation without adding unnecessary complexity.
