One possible answer is:
51.0, 51.1, 51.2, 5.13, and 51.4; the list is from least to greatest.
Explanation:
51.0 can be written as 51.00. Comparing this to 50.98, we can see that 51.00 is larger.
51.1 is larger than 51.0; 51.2 is larger than 51.1; 51.3 is larger than 51.2; and 51.4 is larger than 51.3. All of these numbers are also smaller than 51.6.
