There is an important exception to this rule though. When you group two numbers for comparison and one of those numbers is below 10 and the other is 10 or above, use Arabic numerals. For example, "8 out of 10 teachers recommend summer reading lists," is the correct way to write this statement. The APA format does not use an apostrophe when pluralizing a number. For example, if you were to refer to a decade, it would be correct to use the s, for example, instead of the 's.

Fractions require you to use some judgment. Common fractions such as one-third, one half, and one-fourth should be written out as such. Use a combination of Arabic and written numerals for large numbers. It is correct to write "3 million," for example, rather than using the entire Arabic numeral form.

You should write numbers that begin sentences even if the number is above Note, however, that APA discourages writers from using numbers to begin sentences unless you absolutely must. The same basic rules apply for ordinal numbers. Spell out numbers below You should write ordinal numbers 10 and above in Arabic numeral form.
