Subtract two mixed numbers
Answer: 1 1/6
💡 What it's asking: Turn the mixed numbers into improper (top-heavy) fractions, give them the same denominator, then subtract.
✅ 2⅓ − 1⅙ is a bit more than 2 − 1 = 1, and 1⅙ fits.

Order liquid volumes given in litres and millilitres
Answer: 0.025 l, 0.25 l, 402 ml
💡 What it's asking: To compare volumes, change them all to the same unit (millilitres), then put them in order from smallest to largest.
✅ 0.025 l is a tiny amount (a spoonful), 0.25 l is a cup, and 402 ml is a bit more, so the order makes sense. (If '025 l' meant 25 l, it would go last.)
