NUMBERS GREATER OR LESS THAN NINE/NUMBERS IN A SERIES

Use arabic numerals to express numbers greater than nine. Spell out nine and smaller numbers. However, be consistent in spelling out numbers or using numerals. Normally, use numerals for a series of numbers.

Examples

 Numbers greater than nine: 10 Nine and numbers less than nine: five Series of numbers: 3, 6, 9, 12

ORDINAL NUMBERS

Ordinal numbers follow the general rules described above for cardinal numbers. The preferred form of the ordinals “second” and “third” is with “d” alone, not “nd” and “rd.”

Examples

 Numbers greater than nine: 10th, 22d, 123d Nine and numbers less than nine: first, second, third

REPETITION

Do not repeat in parentheses a number that is spelled out.

Example

 three (not three [3])

AT THE BEGINNING OF A SENTENCE

Do not begin a sentence with a numeral.

Examples

 Six thousand people work at the university. Forty-nine percent of the students are women.

FRACTIONS AND WHOLE NUMBERS WITH FRACTIONS

Ordinarily, spell out a fraction. However, quantities consisting of both whole numbers and fractions should be expressed as numerals.

Examples

 Fractions: two-thirds Whole numbers with fraction: 1 2/38 1/2-by-11-inch paper

DATES, HOURS, DECIMALS, MEASURES, AND PERCENTAGES

Use numerals to express dates, hours, decimals, measures, and percentages.

Examples

 Note: Always spell out the word “percent,” rather than using the symbol (%).
