Part B: Subjective Questions
- 30 cm + 50 cm = 80 cm. The total length is 80 cm.
- 2 kg = 2000 g. 2000 g - 500 g = 1500 g. Sam has 1500 g (or 1.5 kg) left.
- 2 liters = 2000 ml. 2000 ml ÷ 4 = 500 ml. Each glass will have 500 ml.
- The line is 9 cm long.
- (Answers may vary) Liters: Water in a pool, gasoline in a car. Milliliters: Medicine on a spoon, perfume in a bottle.
- ant, dog, elephant
- 1 meter = 100 cm. My desk is longer. 100 cm - 85 cm = 15 cm. It is longer by 15 cm.
- 3 kg x 5 = 15 kg. The total weight is 15 kg.
- (Answers may vary) Because the number would be too large and difficult to write and understand. Kilometers are a much larger unit, making it easier.
- 1 liter = 1000 ml. 1000 ml ÷ 200 ml = 5. It will take 5 cups.
