Three decimal numbers between 16.4 and 16.5 are

16.45 (You would place this between 16.4 and 16.5)
16.46 (You would place this right after 16.45)
16.49 (You would place this right before 16.5)
For this case we need to find numbers between:
 16.4 and 16.5
 Therefore, we can add a number between 1 and 9 located in hundredths.
 We have then that three possible numbers are:
 number 1: 16.42
 number 2: 16.45
 number 3: 16.48
 Answer
