    Usage notes

    [edit]
    • Can be used with either countable or uncountable nouns; however, the word fraction takes the number of the noun it is paired with.
      • If used with a plural countable noun, it needs to take a plural verb.
      • If used with a singular countable noun or an uncountable noun, it needs to take a singular verb.
