Subtract 5 2/3 from 9.

Subtract 5 2/3 from 9.

• A. 3 1/3
• B. 3 2/3
• C. 4
• D. 2 5/6

Answer: (A)

Subtracting a mixed number from a whole number is easiest when you put both numbers over the same denominator. Here, convert everything to thirds: 9 becomes 27/3 and 5 2/3 becomes 17/3. Subtracting gives 27/3 − 17/3 = 10/3, which is 3 and 1/3. So the result is 3 1/3. This matches the exact difference: 9 − 5 2/3 = 3 1/3. The other options don’t fit because they represent different amounts, e.g., 3 2/3 is larger than the actual difference, 4 is even larger, and 2 5/6 is smaller.
