Worked Solution

Step 1: Find the fraction of capacity that was removed. 7/8 - 5/8 = 2/8 = 1/4 of the full capacity. Step 2: Convert the mixed number. 2 3/4 = 2 + 3/4 = 11/4 litres. Step 3: Set up and solve the equation. 1/4 x C = 11/4 C = 11/4 / (1/4) = 11/4 x 4 = 11 litres Verify: 7/8 x 11 = 9.625 L; 5/8 x 11 = 6.875 L; difference = 2.75 = 2 3/4 Check. Answer: Capacity = 11 litres

Correct answer: 11 litres
