Worked Solution

Step 1: Convert both volumes to millilitres. 2 L 50 mL = 2 000 + 50 = 2 050 mL 4 L 750 mL = 4 000 + 750 = 4 750 mL Step 2: Find the total volume. 2 050 + 4 750 = 6 800 mL Step 3: Divide by the cup size to find the number of full cups. 6 800 ÷ 450 = 15 remainder 50 (Check: 15 × 450 = 6 750 ✓ and 16 × 450 = 7 200 > 6 800 ✓) Step 4: Since only full cups are counted, the remainder is ignored. Answer: Mr Tan can fill 15 full cups.

Correct answer: 15
