Here are 10 rules to follow.

**Spell out single-digit numbers.****Use numerals for numbers great than nine.****Spell out numbers that begin a sentence.****Spell out and hyphenate simple fractions.****Use numerals for mixed fractions.****Use numerals for dates.****Use numerals for decimals. Put a zero in front of the decimal if there is no value in front of the decimal point unless the decimal begins with a 0.****Use numerals for the time of day when using a.m. or p.m.****Spell out the time of day when using "o'clock."****Be consistent. Don't mix spelling out numbers and using numerals in the same sentence, even though it seems that you are violating either rule 1 or 2.**
