It is: (15+37)/2 = 26
(2/5 + 8/15) / 2 = 7/15
It is (5 + 10)/2 = 15/2 = 7.5
1 2 3 5 7 11 13 15
The number halfway between 15 and 25 can be found by taking the average of the two numbers. To calculate this, add 15 and 25 together to get 40, then divide by 2 to get 20. Therefore, the number halfway between 15 and 25 is 20.
The halfway number is (15 + 129) /2 = 144/2 = 72
It is (-15 + 20)/2 = 5/2 = 2.5
It is: (15+61)/2 = 38
It is: (15+37)/2 = 26
The number at the midpoint of these two numbers is (15 + 27)/2 = 21
(2/5 + 8/15) / 2 = 7/15
There cannot be any number between two identical numbers.
because the closest number between these 2 numbers is 15
(10+20)/2 = 30/2 = 15
It is (5 + 10)/2 = 15/2 = 7.5
Then number half way between them is their mean average: (-3/7 + -15/14) ÷ 2 = (-6/14 + -15/14) ÷ 2 = -21/14 ÷ 2= -21/28 = -3/4
15It is (6+24)/2 = 15
