10 is the number halfway between -5 and 15.It is: 5
5
No, because halfway is 15. 10 is only 5 higher than 5, but 15 less than 25. So it is not halfway. To find the halfway point (the average), add the two numbers and divide by 2.
It is (5 + 10)/2 = 15/2 = 7.5
2/3 = 10/15 4/5 = 12/15 halfways between 10/15 and 12/15 is 11/15
Halfway between 10 and 15 is (10 + 15) ÷ 2 = 121/2
11.5 is halfway between 8 and 15
(10-20)/2 = -10/2 = negative 5
a number that is halfway between 0 and 5 is 2.5.
