One whole number plus two whole number one over four minus one over three

Let's simplify the expression step by step:

1. Combine the whole numbers:

1 + 2 = 3

2. Find a common denominator for the fractions:

The common denominator for 4 and 3 is 12.

3. Convert the fractions to have a common denominator:

1/4 = (1/4) * (3/3) = 3/12

1/3 = (1/3) * (4/4) = 4/12

So, the expression becomes:

3 + 3/12 - 4/12

4. Combine the fractions:

3/12 - 4/12 = -1/12

5. Combine the whole number and the fraction:

3 - 1/12 = 3 - 1/12

So, the final expression is 3 - 1/12.
