Convert 35.40 kilograms to grams (g).
- A. 354 g
- B. 35,400 g
- C. 3,540 g
- D. 3.54 g
Correct Answer: B
Rationale: To convert kilograms to grams, you need to multiply by 1,000 since there are 1,000 grams in a kilogram. Therefore, 35.40 kg 1,000 = 35,400 grams. Choice A (354 g) is incorrect because it is off by a factor of 10. Choice C (3,540 g) is incorrect as it is off by a factor of 100. Choice D (3.54 g) is incorrect as it represents kilograms instead of grams.

How many liters are in 3,000 milliliters?
- A. 0.3 liters
- B. 30 liters
- C. 3 liters
- D. 0.03 liters
Correct Answer: C
Rationale: To convert milliliters to liters, you need to divide by 1,000 since there are 1,000 milliliters in a liter. Therefore, 3,000 milliliters / 1,000 = 3 liters. Choice A '0.3 liters' is incorrect as it represents 300 milliliters, not 3,000. Choice B '30 liters' is incorrect as it is the result of multiplying by 10 instead of dividing by 1,000. Choice D '0.03 liters' is incorrect as it represents 30 milliliters, not 3,000.
What is 0.5 liters in milliliters?
- A. 500 ml
- B. 50 ml
- C. 5 ml
