Worked Solution
Step 1: Identify denominators 6 and 3. They are different, so we need a common denominator.
Step 2: Find the LCD. Since 6 is already a multiple of 3, LCD = 6.
Step 3: Convert 1/3 to sixths: 1/3 = (1×2)/(3×2) = 2/6.
Step 4: Subtract the like fractions: 5/6 − 2/6 = 3/6.
Step 5: Simplify: 3/6 = 1/2 (divide numerator and denominator by 3).
Final answer: 1/2.
Answer: 1/2
Correct answer: 1/2
