1.1 643 km ÷ 50 = 12,86 km
1.2 2 575 ℓ ÷ 125 ℓ = 20,6 = 20 fulll drums
1.3 37,5 mℓ × 275 = 10 312,5 mℓ = 10,3125 ℓ
1.4 538 900 ℓ - 98 476 ℓ = 440 424 ℓ = 440,424 kℓ
1.5 900 mℓ + 300 mℓ + 480 mℓ + 1 140 mℓ
1.6 = 2 820 mℓ = 2,820 ℓ

Assessment
Learning Outcome 4: The learner will be able to use appropriate measuring units, instruments and formulae in a variety of contexts.
Assessment Standard 4.5: We know this when the learner solves problems involving selecting, calculating with and converting between appropriate S.I. units listed above, integrating with appropriate Technology and Natural Sciences contexts.
