Answer 2

To solve the expression 1/2 - (-3/4) with the complete solution, we can follow these steps:

Step 1: Simplify the expression within the parentheses. Recall that the negative sign in front of a fraction is equivalent to multiplying it by -1. Therefore, -(-3/4) becomes 3/4.

Step 2: Subtract the fractions. To subtract fractions, we need to find a common denominator. The common denominator for 2 and 4 is 4. Now we can rewrite the expression as follows: 1/2 - 3/4 = (1 * 2)/(2 * 2) - 3/4 = 2/4 - 3/4.

Step 3: Perform the subtraction. Since the denominators are the same, we can subtract the numerators directly and keep the common denominator: 2/4 - 3/4 = (2 - 3)/4 = -1/4.

Therefore, the complete solution to 1/2 - (-3/4) is -1/4.
