Final answer:
To subtract mixed numbers, find a common denominator and subtract the numerators. Simplify the answer if possible.
Step-by-step explanation:
To subtract mixed numbers, you need to find a common denominator for the fractions involved. In this case, the common denominator is 6 because both 3 and 2 divide evenly into it. We can convert 23/3/3 to 38/6 and 11/3/2 to 11/6. Now, we can subtract the numerators: 38 - 11 = 27.
The denominator remains the same: 6. So, the answer is 27/6, which can be simplified to 4 and 3/6. The mixed number form of this answer is 4 and 1/2.
