(12 + 148)/2 = 160/2 = 80
It is: 24
(0 + 12)/2 = 6 this is different from halfway between 1 & 12 because of starting the range at 0
It is 10, the number halfway between them.
It is (12 + 13)/2 = 25/2 = 12.5 or 12½

No.
This is the same as finding the "mean" of the number. So we add the two numbers together then divide that by 2. If we want the number halfway between 5 and 7, we add them together, 5+7=12 then divide by 2, 12/2=6. So 6 is between 5 and 7.

The number halfway between is 1/2*(1/8 + 7/12) = 1/2*(3/24 + 14/24) = 1/2*(17/24) = 17/48
