What is the midpoint between -1 and 0
Answer and explanation
Correct answer: \(-\frac{1}{2}\)
The midpoint of two numbers \(a\) and \(b\) is \(\frac{a+b}{2}\). Therefore, the midpoint of \(-1\) and \(0\) is \(\frac{-1+0}{2}=-\frac{1}{2}\). \(\frac{1}{2}\) is the midpoint between 0 and 1, so it is not correct here. Exam tip: on a number line, a midpoint is equally distant from both numbers.
