The answer is 1414
To find the number halfway between any two numbers x and y, add x and y, then divide the answer by 2. So for 21 and 35, 21+ 35 = 56. 56/2 = 28. You can check your answer by seeing that 21 + 7 = 28 and 35 - 7 = 28.
It is 20, the number halfway between the two middle values.
19.5 is halfway between 18 and 21
There is no distance between them.
The fraction 23/35 is halfway. 3/5 = 21/35 5/7 = 25/35
The number halfway between 7 and 31 is 19.
The number halfway between 13 and 21 can be found by taking the average of the two numbers. Add 13 and 21 together to get 34, then divide by 2 to get 17. Therefore, the number halfway between 13 and 21 is 17.
