-5
5
Well, honey, if you wanna find the number smack dab in the middle of -5 and 15, you just average those two bad boys. So, (-5 + 15) / 2 = 5. There you have it, sweet cheeks, 5 is the magic number that's halfway between those two extremes.
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
11.5 is halfway between 8 and 15
(10-20)/2 = -10/2 = negative 5
15
It is 15
The halfway number is (15 + 129) /2 = 144/2 = 72
Halfway between 15 and 30 is the average of the two numbers. To find the average, you add the two numbers together and then divide by 2. In this case, (15 + 30) / 2 = 45 / 2 = 22.5. Therefore, 22.5 is halfway between 15 and 30.
-5 It is 15 more than -20 and 15 less than 10 To find a halfway point (which is also the average), add the numbers together and divide by 2. -20 + 10 = -10 and -10/2 = -5
