Which rational number lies between -1 and 2
Answer and explanation
Correct answer: \(\frac{1}{2}\)
For \(\frac{1}{2}=0.5\), we have \(-1 < \frac{1}{2} < 2\), so it is a rational number between -1 and 2. \(-\frac{3}{2}\) is less than -1, while \(\frac{5}{2}\) is greater than 2. Exam tip: To check whether a number lies between two values, compare it with both endpoints.
