In this activity, we will be finding the number halfway between two given numbers.

 

The number halfway between 74 and 75 is 74.5

The number halfway between 74 and 80 is 77

The number halfway between 0.7 and 0.8 is 0.75

 

How to work it out

You can add the two numbers and then divide the result by 2.


Or you can find the gap between the two numbers and add half of this to the smaller number.

 

For example, what number is halfway between 87 and 91?

87 + 91 = 178 ÷ 2 = 89

 

The gap between 87 and 91 is: 91 - 87 = 4

Half of 4 is 2.

87 + 2 = 89

 

Both methods work, so you should do whichever one works best for you - aren't we kind?!
