Answer:
19/38, 8/20, --5 4/10,
Explanation:
First you can tell that -5 4/10is the least because it is a negative number. Then, you can see that 19/38 is the greatest because if you find out what half of 38 is it is 19 so 1/2 and 1/2 is greater then 8/20 because half of 20 is ten and 8 is not 10.
Hope this helps
