Which expression represents half of (r)?

Answer and explanation

Correct answer: \(\frac{r}{2}\)

To find half of a variable, divide it by 2. Therefore, half of \(r\) is \(\frac{r}{2}\), so option D is correct. \(2r\) means twice \(r\), while \(r+2\) and \(r-2\) add or subtract 2. Exam tip: translate “half” as division by 2.
