Best practice

When using "about half", ensure the context makes it clear what the whole is. For example, "About half of the students passed the exam" clearly indicates that the 'whole' is the student population who took the exam.

Common error

Avoid using "about half" when precision is required. If the exact percentage is known (e.g., 48% or 52%), using the precise number will add credibility to your writing. Use "about half" only when a rough estimate is sufficient.
