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.
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.

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.
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.

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.
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.
