Least common measure for 10, 5, 11 and 2 is 110 (click here to see the calculation)
Monday: 7/10 = (7*11)/(10*11) = 77/110
Tuesday: 3/5 = (3*22)/(5*22) = 66/110
Wednesday: 9/11 = (9*10)/(11*10) = 90/110
Thursday: 1/2 = (1*55)/(2*55) = 55/110
Since 90 > 77 > 66 > 55 we conclude that on C. Wednesday she had the most homework.
