To evaluate the expression 4 - 1 1/4 + 1/2, you can follow these steps:

Step 1: Convert the mixed number 1 1/4 to an improper fraction.

1 1/4 = (1 * 4 + 1) / 4 = 5/4

Step 2: Rewrite the expression using the improper fraction.

4 - 5/4 + 1/2

Step 3: Find a common denominator for the fractions, which is 4.

4 - (5/4 * 1) + (1/2 * 2)

Step 4: Simplify the expression.

4 - 5/4 + 2/2

Step 5: Combine the fractions with common denominators.

4 - 5/4 + 2/2 = 4 - 5/4 + 4/4

Step 6: Subtract and add the numerators, keeping the common denominator.

4 - 5/4 + 4/4 = 4 - 1/4

Step 7: Perform the subtraction.

4 - 1/4 = (4 * 4 - 1) / 4 = 15/4

Therefore, the value of the expression 4 - 1 1/4 + 1/2 is 15/4.

4 - 5/4 + 4/4 = 4 - 1/4

Step 7: Perform the subtraction.

4 - 1/4 = (4 * 4 - 1) / 4 = 15/4

Therefore, the value of the expression 4 - 1 1/4 + 1/2 is 15/4.

However, when evaluating the expression further:

15/4 = 3 and 3/4

Therefore, the value of the expression 4 - 1 1/4 + 1/2 is 3 3/4.
