What is the result of 4 minus 1/3?

A. 3 2/3
B. 1/3
C. 3
D. 2/3

The correct answer is: A. 3 2/3

To find the result of 4 minus 1/3, you first need to convert the whole number 4 into a fraction that has the same denominator as 1/3. The value 4 can be expressed as 4/1, and to convert this into a fraction with a denominator of 3, you multiply both the numerator and denominator by 3, resulting in 12/3. Now you have the operation: 12/3 - 1/3 With the same denominator, you can simply subtract the numerators: 12 - 1 = 11 This gives you 11/3 as the answer. To express this as a mixed number, you divide 11 by 3. This division gives a quotient of 3 (which is the whole number part) and a remainder of 2. Thus, 11/3 can be expressed as 3 2/3. Therefore, the result of 4 minus 1/3 is indeed 3 2/3, confirming that the correct answer is the first choice.
