Compute (1/2) + (3/4).

Compute (1/2) + (3/4).

• A. 5/4
• B. 1/4
• C. 3/4
• D. 2

Answer: (A)

Combining fractions with different denominators requires a common denominator. Here, use 4 as the shared bottom. Convert 1/2 to 2/4, then add 2/4 and 3/4 to get 5/4. The sum can be kept as the improper fraction 5/4, or written as a mixed number 1 1/4 (which is 1.25 in decimal). The other options don’t match this total: 1/4 is 0.25, 3/4 is 0.75, and 2 is 2 (which would be 8/4).
