Halfway between 30 and 80 is (30 + 80) ÷ 2 = 55.
100 80 + 20 = 100 120 - 20 = 100
(80 + 90) / 2 = 85Therefore, the number between 80 and 90 is 85.
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.
