Question 6: write four instances where you would use a hyphen and provide an example for each one.

1. When using a compound adjective (used when the adjective precedes the noun it qualifies) e.g This is an off-campus apartment.

2. To tell the ages of people and things (used when the time period is not in plural form) e.g  We have a six-year-old child

3. When a range of number is being expressed. e.g 6:20-8:15 p.m.

4. To express any compound number from twenty-one through ninety-nine. e.g four thousand six hundred fifty-three people

Is there more to this?
