The distance between 1 and .5 is (1 - .5)/2 which is .25. Add that to .5 to get the number halfway between the points: .5 + .25 = .75.So the point halfway between is .75 or 3/4.

The halfway number is 1/2*(750000 + 1000000) = 1/2*1750000 = 875000
Halfway between one and a quarter and one and three quarters lies one and a half.
The number halfway between is 1/2*(1/8 + 7/12) = 1/2*(3/24 + 14/24) = 1/2*(17/24) = 17/48
It is (1 + 24)/2 = 25/2 = 12.5
There are infinite numbers between 1/3 and 1/4, but the number exactly halfway between them is 7/24.
0.75 ---------------the halfway number
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.
The distance between 1 and .5 is (1 - .5)/2 which is .25. Add that to .5 to get the number halfway between the points: .5 + .25 = .75.So the point halfway between is .75 or 3/4.

The number that is halfway between one and one half (1½) and one (1) is one and one quarter (1¼)
There are an infinite number of numbers between 1 and 2. The number which is exactly halfway is 1.5.
1/4
It is: (1/4+1/6)/2 = 5/24
