Question

Select the locations on the number line to plot the points 10/2 and −9/2 .

Answer 1

The number line is in the attached picture.

Explanation:

We have the points 10/2 and −9/2.

The point 10/2 can be expressed as:

`(10)/(2) =5`

The point -9/2 can be expressed as:

`- (9)/(2)= - (8+1)/(2)= -((8)/(2) + (1)/(2))= -(4 + (1)/(2) )=-4(1)/(2)`

So for the first point we have to count 5 places from zero to the right.

For the second point, we have to count 4 places and a half from zero to the left.

Answer 2

5 and -4.5

Explanation:

10/2=5

and -9/2=-4.5

-5 -4.5 -4 -3 -2 -1 0 1 2 3 4 5
