where should a hyphen be placed in the following sentence? “there are fifty two weeks in a year and twelve months, so some months have four weeks while others have four and a half.” a. four-and-a-half b. four-weeks c. fifty-two d. twelve-months

Answer 1

The hyphen should be placed in C) fifty-two.
When you have compound numbers, meaning there are two words to denote a single number, starting from twenty-one, you need to use a hyphen.
