Well the way I look at it is...

find the total distance between the two numbers and divide by 2.

so...

-15 is 15 away from 0, and 20 is 20 away from 0.

I then add 15 and 20 together to get 35.

I take 35 and divide by 2 to get 17.5.

From here you can either add 17.5 to -15 or subtract 17.5 from 20.

The answer is 2.5

Another way to look at this is with a line so...

each period is equal to 1 number, the 0 in the line is the number 0

-15..............0...................20

You can see that the distance is greater on the right side because 20 is farther away from 0 than -15 is. You have to find the total distance between the -15 and 20 and divide by 0.

Q: What is the halfway point between -15 and plus 20?

Geographically speaking, there is no city on the exact point between St. George and Provo, But taking I-15, Cove Fort is the closest halfway point between the two locations.

No, because halfway is 15. 10 is only 5 higher than 5, but 15 less than 25. So it is not halfway. To find the halfway point (the average), add the two numbers and divide by 2.

It is 15

The halfway number is (15 + 129) /2 = 144/2 = 72

12.5 comes halfway because if u imagine 15 was 14 just find what is halfway to that but remember it is 15 the actually the number then put the point five so it is 12.5
