Halfway between 30 and 80 is (30 + 80) ÷ 2 = 55.
(30+60)/2 = 45
25
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.
It is 25

42 is exactly halfway between 32 and 52.42
Halfway between 30 and 80 is (30 + 80) ÷ 2 = 55.
The number 30, itself, is a decimal number. So it is the nearest.There is no other "nearest" number. If there were, the number halfway between that number and 30 would be nearer to 30. And then the number halfway between that number and 30 would be nearer still. And so on.
