Question

Which rational number is one-half of the way between 2 and 6.5: 2.25, 4.25, 4.5, or 4.75? And please explain.

Answer 1

To find the average, add and divide by 2, so (2+6.5)/2 = 4.25

Answer 2

The way between 2 and 6.5 is 4.5.
Half of that way is 2.25.

Answer 3

We have 2 numbers: 2 and 6.5
One-half means the answer divides that into 2 parts.
So, you need to find the distance between 6.5 and 2, so
6.5-2 = 4.5
Half of 4.5 is 4.5/2 = 2.25
Got it? :)
