How should you handle numbers in running text under the provided style guidance?

• A. Spell out numerals for all numbers.
• B. Use numerals for every number.
• C. Spell out numbers one through nine in running text; use numerals for 10 and above.
• D. Use Roman numerals for numbers.

Answer: (C)

In running text, small numbers read more smoothly when written as words, while larger numbers are clearer as numerals. So spell out numbers one through nine and use numerals for 10 and above. This balances readability with quick recognition of quantity and keeps the prose from getting bogged down by long strings of words or digits. For example, you’d write “three apples and 12 oranges” rather than “three apples and twelve oranges” or “3 apples and 12 oranges” in most styles. Using digits for every number or turning everything into Roman numerals disrupts the flow of normal prose and looks out of place, while spelling everything out can make text feel verbose.
