Worked Solution
Step 1: Both fractions already have the same denominator (4), so add the numerators directly: 9/4 + 5/4 = 14/4.
Step 2: Check whether 14/4 can be simplified. gcd(14, 4) = 2, so divide top and bottom by 2: 14/4 = 7/2.
Step 3: Convert 7/2 into a mixed number. 7 ÷ 2 = 3 remainder 1, so 7/2 = 3 1/2.
Step 4: Confirm simplest form. 1/2 cannot be simplified further.
Final answer: 3 1/2.
Answer: 3 1/2
Correct answer: 3 1/2
