Question

On a number line what is the lenght of line segment joining -1/2 & -5/2

Answer 1

Step-by-step explanation:

$length \: = - \frac{1}{2} - ( - \frac{5}{2} ) \\ = - \frac{1}{2} + \frac{5}{2} = \frac{5 - 1}{2} = \frac{4}{2} = 2 \\ hence \: the \: length \: of \: line \\ \: segment \: joining \: - \frac{1}{2} \: and \: - \frac{5}{2 } \\ \: is \: 2 \: units.$
