Answer 1

It is given that red dot is about halfway between 12 and 13.

Draw a number line.Mark points on it on as 1,2,3,.....12,13,...20.

Label 12 as point M and label 13 as N.

Mid point of MN=
`(12+13)/(2)`

=25/2

=12.5

Mark 12.5 as T.

MT =NT

The Red dot is at point N at a distance of 12.5 units from the origin.
