Today’s EyeEdit writing tip: Know when to express numbers in words or in numerals.
Different guidelines can exist for expressing numbers. In general, you will use figures for large numbers and for precise numbers such as money, serial numbers, and phone numbers. You will use words for numbers from one to nine, for approximate amounts, and for numbers that begin a sentence.
Below are some of the usual rules for numbers, with examples:
| Rules | Examples
|
| 1. Write in words the numbers below ten. Use numerals for numbers above nine. | I can eat three patties.
He bought 12 patties. |
| 2. Be consistent in writing numbers or numerals. So if you start out with writing a numeral for a number above nine, continue to use numerals even if another number in the sentence is single-digit. | I have 11 pencils and 2 erasers.
I have eleven pencils and two erasers. |
| 3. Always spell out simple fractions. Remember to use hyphens. | Two-thirds of the class went on the outing
One-half of the cookies are missing. |
| 4. Express a mixed whole number and fraction in figures, unless it begins a sentence. | The store offered a 7 ½ per cent discount.
Seven and one-half per cent is the usual discount. |
| 5. You can express large numbers in numerals or in words. Consistency is important. | Harry inherited between two and four million dollars from his uncle.
Harry inherited between $2 million and $4 million dollars from his uncle. |
| 6. Write decimals as figures. Place a zero in front of the decimal unless the decimal begins with a zero. | Sales increased at a rate of 0.93 per month.
Sales increased a mere .03 per month. |
| 7. Be consistent when writing dates. | The new semester starts on September 2.
The new semester starts on the 2nd of September. |
| 8. Decades can be written in words or as numerals with an apostrophe to show the missing numbers. Note: there is no apostrophe between the number and the s. | Rock and Roll was popular during the fifties.
Rock and Roll was popular during the ‘50s. |
| 9. Use numerals or words for time except o’clock when the number is always written in words. Exact times are always written in numerals. | She leaves for work at about seven thirty in the evening.
She arrived at work at 9:00 A.M. (or a.m.) They go jogging at six o’clock in the morning. |
| 10 Write out a number if it begins a sentence. | Seventy-two teachers attended the conference. |
