What number is halfway in between 4.5 and 6.7

6.7 - 4.5 = 2.2

2.2 / 2 = 1.1

6.7 - 1.1 = 5.6

4.5 + 1.1 = 5.6

The answer is 5.6

First you subtract 6.7 by 4.5 and then split ur answer in half. in this case ur answer is 2.2 split in half is 1.1 so that means ur answer when subtracted by 6.7 will equal 1.1 and when u subtract it by 4.5 will also equal 1.1. once you do all of that you will find your answer to be 5.6, if you subtract 6.7 by 5.6 you get 1.1 and if you subtract 5.6 by 4.5 u get 1.1 as well indicating that to be your answer
