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
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
Halfway between 10 and 15 is (10 + 15) ÷ 2 = 121/2
10 is the number halfway between -5 and 15.It is: 5
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
