First, you need to find their differences by subtracting -20 from 12.
12-(-20)
12+20
32
So we know they have 32 difference. Now divide 32 by 2 since you're talking about HALF WAY in between the numbers, and subtract that number from 12.
32/2=16
12-16=-4
-4 is your answer. To check your work, as yourself what's the difference between 12 and -4 and -20 and -4. They both are 16 numbers away from each other, therefore you can be certain that the number half way in between 12 and -20 is -4.
20
The answer is 26 because you find the difference between 20 and 32 (12) then you half that (6) then you add that to the lowest number (26) and there is your answer
15
It is: 50
17
the number between 2 and 20 is 11
The halfway point between two numbers is found by calculating the average of the two numbers. In this case, the average of -20 and 10 is (-20 + 10) / 2 = -10 / 2 = -5. Therefore, the number halfway between -20 and 10 is -5.
30
The number halfway between 18 and 22 can be found by taking the average of the two numbers. Adding 18 and 22 together gives us 40, and dividing by 2 gives us 20. Therefore, the number halfway between 18 and 22 is 20.
35
40
0.3 is halfway between 20% and 40%
