The halfway number is (15 + 129) /2 = 144/2 = 72
10 is the number halfway between -5 and 15.It is: 5
Halfway between 10 and 15 is (10 + 15) ÷ 2 = 121/2
A halfway is something you can split into two and add it back together to make a whole number.(Maths answer)Eg: Half of 30 =15 15 + 15 = 30 15 x 2 = 30A different halfway is like halfway across something,meaning you are halfway through something and another distance of what you have walked already is what you must walk next.Eg: Sally has to walk 100 meters to get back to her house, she has already walked 50 meters and now she must walk another 50 meters because she has walked halfway through.

12.5 comes halfway because if u imagine 15 was 14 just find what is halfway to that but remember it is 15 the actually the number then put the point five so it is 12.5
