The results of 12 days are 

1 1/2 quarts, 2 1/4 quarts, 2 quarts, 1 1/2 quarts, 1 3/4 quarts, 1 1/2 quarts, 1 1/4 quarts, 2 quarts, 2 1/4 quarts, 1 1/2 quarts, 2 quarts, and 1 1/2 quarts

This can also be written as 

3/2 quarts, 9/4 quarts, 2 quarts, 3/2 quarts, 7/4 quarts, 3/2 quarts, 5/4 quarts, 2 quarts, 9/4 quarts, 3/2 quarts, 2 quarts, 3/2 quarts 

Making denominator equal to 4 in all the results 

6/4 quarts, 9/4 quarts, 8/4 quarts, 6/4 quarts, 7/4 quarts, 6/4 quarts, 5/4 quarts, 8/4 quarts, 9/4 quarts, 6/4 quarts, 8/4 quarts, 6/4 quarts

Given that average = 1 3/4 quarts  = 7/4 quarts

On how many days did Keisha drink at least the average amount of water??

Now simply we can compare the results with the average value and count 

Number of days = 6 days ( all in bold) 

Now On day 13, Keisha drinks 1 quart of water.  means 4/4 quarts of water 

new average = (12  x 7/4 + 4/4)/13 = 22/13 = 1 9/13 

New average = 1 9/13  quarts
