It is: 15
-12.5
It is (5 + 10)/2 = 15/2 = 7.5
5 It is 15 more than -10 and 15 less than +20. To find the halfway point (the average), add the two numbers and divide by 2. -10 + 20 = 10 divided by 2 = 5
2/3 = 10/15 4/5 = 12/15 halfways between 10/15 and 12/15 is 11/15
10 is the number halfway between -5 and 15.It is: 5
Halfway between 10 and 15 is (10 + 15) ÷ 2 = 121/2
15
5
It is: 15
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.
-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
-12.5
It is (5 + 10)/2 = 15/2 = 7.5
5 It is 15 more than -10 and 15 less than +20. To find the halfway point (the average), add the two numbers and divide by 2. -10 + 20 = 10 divided by 2 = 5
(10-20)/2 = -10/2 = negative 5
2/3 = 10/15 4/5 = 12/15 halfways between 10/15 and 12/15 is 11/15
