Question

6. a) Use a number line to list the whole numbers between 16 and 25 What number is halfway between 16 and 25? Use the number line in part a) to help you.

Answer 1

The number line is drawn as shown below

Since the interval between each whole number on the number line is 1. the halfway distance would be 1/2 = 0.5

Thus, the number that is halfway between 16 and 25 lies between 20 and 21

The difference between 16 and 25 is 25 - 16 = 9

9/2 = 4.5

Thus, the number that is halfway between 16 and 25 is 16 + 4.5 = 20.5

The answer is 20.5
