Therefore, to find out how many grams are in 5 kilograms, we multiply 5 by 1000, which equals 5000 grams. The correct answer is C. A: 50 grams - Incorrect. 5 kilograms is equal to 5000 grams, not 50 grams. B: 500 grams - Incorrect. 5 kilograms is equal to 5000 grams, not 500 grams.

Question 2 of 5
How many milliliters are in 0.5 liters?
Correct Answer: B
Rationale: To convert liters to milliliters, you need to know that 1 liter is equal to 1000 milliliters. So, to find how many milliliters are in 0.5 liters, you multiply 0.5 by 1000, which equals 500 milliliters. Therefore, the correct answer is B: 500 mL. Choice A (50 mL) is incorrect because it is 10 times less than the correct answer. Choice C (5,000 mL) is incorrect because it is 10 times more than the correct answer. Choice D (5 mL) is incorrect because it is 100 times less than the correct answer.
Question 3 of 5
How many millimeters are in 0.75 centimeters?

Rationale: To convert from centimeters to millimeters, you multiply by 10 since there are 10 millimeters in 1 cm. Therefore, to find how many millimeters are in 0.75 cm, you multiply 0.75 by 10, which equals 7.5 mm. Therefore, the correct answer is C: 75 mm. Choice A: 7.5 mm is the result of the correct conversion. Choice B: 0.75 mm is incorrect as it's the original value, not the converted value. Choice D: 75 cm is incorrect as the question asks for millimeters, not centimeters.
