1 ℓ of soup is shared equally among 2 cousins. How much soup does each of them get? Give your answer in millilitres.
Need a hint?
Share first (1 ÷ 2), then change the fraction of a litre into millilitres.
Worked answer
- Each gets 1 ÷ 2 = 1/2 ℓ.
- 1/2 ℓ = 1/2 × 1000 mℓ = 500 mℓ.
Answer: 500 mℓ

Habit
Converting units (kg, ℓ, m, cm³)
Each share is 1 ÷ 2 = 1/2 ℓ. The question wants millilitres: 1 ℓ = 1000 mℓ, so 1/2 × 1000 = 500 mℓ.
