10 is the number halfway between -5 and 15.It is: 5
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.
a number that is halfway between 0 and 5 is 2.5.
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 halfway number between 3/4 and 3/5 is 27/40.
Add the two and divide by two. Let's try it: 5+7=12 12÷2=6 --halfway between 5 and 7 is 6. Again: 125+239=364 364÷2=182 -- halfway between 125 and 239 is 182. You can also do this long form: 239-125=114 & 114÷2=57 then 125+57=182 -- back to halfway.
