Write the Right Word: Plurals of Numbers

Forming plural numbers is a lot easier than forming plural words. You simply add an “s” to numbers.

The other key rule to remember is that you do not need to add an apostrophe before the “s.”

Here are some examples:

  • Years: The insect wasn’t common in North Dakota until the late 1980s.
  • Temperatures: Temperatures are expected to drop to the low 30s tonight.
  • Sizes: All the shoe store had left were two pairs of size 7s.
  • Designations: Delta Airlines is phasing out its 747s.

If you are making plurals of numbers that are spelled out, then the rules for making plurals of words apply. For example, sixes (add an “es” to words ending in ch, s, sh, ss, x and z).
