It is 70
Well, isn't that just a happy little question! To find the number halfway between 20 and 80, we add them together to get 100, then we divide by 2 to find the middle point. So, the number halfway between 20 and 80 is 50. Just like painting, sometimes finding balance is the key to creating a beautiful picture.

60(40+80)/2 = 60
115 is halfway between 80 and 150
Halfway between 30 and 80 is (30 + 80) ÷ 2 = 55.
80 It is 20 more than 60 and 20 less than 100 To find a halfway point (which is also the average), add the numbers together and divide by 2.60 70 *80* 90 100As you can see, the answer is 80.
(80 + 90) / 2 = 85Therefore, the number between 80 and 90 is 85.
