The number that is halfway between one and one half (1½) and one (1) is one and one quarter (1¼)
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.
If that's 0 and 12, halfway is 6/1 If that's 0 and 1/2, halfway is 1/4

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.

Halfway between 7.6 and 2.4 is 1/2 x (7.6 + 2.4) = 1/2 x 10 = 5
