The table shows the changes from the average water level of a pond over several weeks. Order the numbers from least to greatest.

Answer:
-7/5, -1.45, -1 5/11, -1 91/200 (Least to greatest)
Step-by-step explanation:
Turn all of the numbers into decimals. It'll be easier to sort then.
-7/5 is -1.4
-1 5/11 is -1.45... (meaning -1.45 with a bar notation over the .45)
-1.45
-1 91/200 is -1.455
Now you can just sort them. Be sure that when you put your answer down, that you convert them back into their original form.
Hope this helped. :)
