Question

On this number line ,what is the coordinate of point a?

Answer 1

Given:

The objective is to find the coordinate of the point A on the number line.

Since point A lies in between +2 and +3.

Then, the mean value of +2 and +3 is,

`\begin{gathered} \text{Mean}=(2+3)/(2) \\ =(5)/(2) \\ =2.5 \end{gathered}`

Hence, the coordinate of point A is 2.5.
