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.
It is 15
41.5
It is 13
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 number halfway between 4 and 7 is the average of the two numbers. To find the average, you add the two numbers together and then divide by 2. In this case, (4 + 7) / 2 = 11 / 2 = 5.5. Therefore, 5.5 is the number halfway between 4 and 7.
The average of -7 and 4 is -1.5 .
It is 15
10.95
41.5
the number that is halfway between -4 and 0 is -2
It is 13
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

Halfway between 1 and 4 is the midpoint, which can be calculated by adding the two numbers and dividing by 2. In this case, (1 + 4) / 2 = 2.5. Therefore, 2.5 is the number that is exactly halfway between 1 and 4.
To locate the average (halfway point) between two fractions, change them both to equivalent fractions: fractions with a common denominator. The LCM is best, or you can multiply the denominators together to find a common one. Then add the fractions together and divide by 2. If the numerator of the sum is odd, divide by two by multiplying the denominator by 2. examples: 1/5 and 3/5 -- the average (halfway point) is obviously 2/5 1/3 and 2/3 -- the sum is 3/3 = 1, so the midway point is 1/2 (you can see that the midway point between 2/6 and 4/6 is 3/6) 1/5 and 3/7 -- 7/35 + 15/35 = 22/35 and the halfway point is 11/35 (the midway point between 7 and 15 is 11) 1/6 and 5/11 -- 11/66 + 30/66 = 41/66 and the halfway point is 41/132 Checking: 1/6 = 22/132 and 5/11 = 60/132 -- the midpoint 41/132 is 19/132 more than 1/6 and 19/132 less than 5/11
