It is: 1.75
The number halfway between 18 and 60 is (18 + 60)/2 = 39.
17. A 4x4 rectangle has a perimeter of 16 units and an area of 16 square units. A 3x6 rectangle has a perimeter of 18 units and an area of 18 square units. The number 17 is halfway between 16 and 18.
(13 + 23)/2 = 18
The single number directly between those two numbers is 18.
It is 13.5 which is the value halfway between the two middle values 12 and 15.
Halfway between 18 and 28 is (18 + 28) ÷ 2 = 23.
The number halfway between 18 and 21 can be found by taking the average of the two numbers. To do this, add 18 and 21 together to get 39, then divide by 2 to get 19.5. Therefore, the number halfway between 18 and 21 is 19.5.
The number halfway between 18 and 60 is (18 + 60)/2 = 39.
18 and 54
17. A 4x4 rectangle has a perimeter of 16 units and an area of 16 square units. A 3x6 rectangle has a perimeter of 18 units and an area of 18 square units. The number 17 is halfway between 16 and 18.
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.
(13 + 23)/2 = 18
It is: (18+21)/2 = 19.5
The number exactly halfway between two numbers is found by taking the average of the two numbers. In this case, the average of 14 and 18 is (14 + 18) / 2 = 32 / 2 = 16. Therefore, the number exactly halfway between 14 and 18 is 16.
(5 + 13)/2 = 18/2 = 9
The single number directly between those two numbers is 18.
