Subtracting Mixed Numbers
To subtract mixed numbers, we first need to convert them into improper fractions.

Converting Mixed Numbers to Improper Fractions
- 11 20/20 = 11
- 1 4/5 = 1(5*1 + 4)/5 = 9/5

Subtracting Improper Fractions
Now that we have converted the mixed numbers to improper fractions, we can subtract them.
11/20 - 9/5 = (11*5 - 9*20)/20*5
= (55 - 180)/100
= -125/100
= -1 25/100
= -1 1/4

Final Answer
Therefore, 11 11/20 - 1 4/5 = -1 1/4.
