Correct Answer: A

Rationale: To convert meters to millimeters, we know that 1 meter is equal to 1000 millimeters. Therefore, to find how many millimeters are in 5 meters, we multiply 5 by 1000 which equals 5000 millimeters. Choice A (5000 mm) is correct. Choices B, C, and D are incorrect as they do not accurately convert 5 meters to millimeters. Choice B (4000 mm) is incorrect because it underestimates the conversion. Choice C (5500 mm) is incorrect as it overestimates the conversion. Choice D (6000 mm) is also incorrect as it overestimates the conversion.

Correct Answer: B

Rationale: To find 70% of 65, you multiply 65 by 0.70 (which is the decimal form of 70%). 65 * 0.70 = 45.5 Therefore, the correct answer is B: 45.5. Choice A (40.5), C (50), and D (55) are incorrect as they do not result from the correct calculation of 70% of 65.

Correct Answer: A

Rationale: Certainly! To compare, we need to convert both fractions to a common denominator. LCM of 8 and 100 (8*25) is 100. Sally ate (5/8)*100 = 62.5%. John ate 75%. Clearly, 75% is more than 62.5%. So, John ate more. Other choices are incorrect as they do not consider the actual percentages consumed by Sally and John.

Correct Answer: A

Rationale: To find the number that 44 is 25% of, we divide 44 by 0.25 (which is 25% expressed as a decimal). 44 / 0.25 = 176. Therefore, 44 is equal to 25% of 176. Option A (176) is the correct answer. Option B (150), C (180), and D (120) are incorrect as they do not result in 44 when multiplied by 0.25.

Correct Answer: A

Rationale: To convert pints to ounces, we know that 1 pint equals 16 ounces. Therefore, 3/4 of a pint is equal to 3/4 * 16 = 12 ounces. So, the correct answer is A: 12 ounces. Option B (16 ounces) is the total amount in 1 pint, not 3/4 pint. Option C (14 ounces) and D (10 ounces) are incorrect conversions.
