It is 13
the number between 2 and 20 is 11
The number 8 is halfway between 5 and 11. It is 3 more than 5 and 3 less than 11. To find a halfway point (which is also the average), add the numbers together and divide by 2.
It is (10.7 + 11)/2 = 10.85
the halfway point is 10.5 or 10 and a half
The number halfway between 9 and 13 can be found by calculating the average of the two numbers. To do this, you add 9 and 13 together to get 22, and then divide by 2 to find the average, which is 11. Therefore, the number halfway between 9 and 13 is 11.

It is 47, the number halfway between the two of them.
the number between 11 and 12 is obvious. it is 11 and a half
the halfway point is 10.5 or 10 and a half
There is no "the" rational" number since there is an infinity of them. Start with the number halfway between the two: (1/10+1/11)/2 = 21/220. Then try halfway between 1/10 and 21/220, and then halfway between 1/10 and that on. And so on.
Add 1/4 and 2/3. This results in 11/12. Then divide by 2 (or multiply by 1/2). The answer is 11/24 or about .458333.
Well, darling, the number halfway between 11 and 15 is 13. You see, it's smack dab in the middle of those two numbers, like the cherry on top of a sundae. So, there you have it, 13 is the magic number in this case.
Add and divide by '2' Hen (11 + - 4) / 2 = 7/2 = 3.5 is the halfway point. Here is the number line -4,-3,-2,-1,0,1,2,3,(3.5)4,5,6,7,8,9,10,11 Notirce there are 8 1/2 places from either end to the mid point.
