Add 55 and 21, then divide by 2 = 38
38
19.5 is halfway between 18 and 21
Halfway between 30 and 80 is (30 + 80) ÷ 2 = 55.
There is no distance between them.
It is: 55
51 is half way between 47 and 55.
75
55
It is 55 minus 21 = 34
The halfway point between 50 and 60 is (50 + 60) ÷ 2 = 55
55
It is 55, the number halfway between them.
