Correct Answer: B

Rationale: To calculate the percentage Jill saved, we divide the amount saved ($140) by her total earnings ($400) and multiply by 100. So, (140/400) * 100 = 35%. Choice B is correct as it accurately represents the percentage of earnings saved. Choice A (30%) is incorrect because it's lower than the actual percentage saved. Choice C (40%) is incorrect because it's higher than the actual percentage saved. Choice D (25%) is also incorrect because it's lower than the actual percentage saved.

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: A

Rationale: To add 1.332 and 0.067, start from the rightmost digit and move left. Add 2 + 7 (9), then 3 + 6 (9), and 1 + 0 (1). The sum is 1.399, making choice A the correct answer. Choices B, C, and D are incorrect as they do not match the correct sum obtained through the addition process.

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.

Correct Answer: B

Rationale: To convert pints to ounces, we know that 1 pint is equal to 16 ounces. Therefore, 3 pints would be 3 x 16 = 48 ounces. This makes choice B the correct answer. Choice A (24 ounces) is incorrect as it represents only 1 pint, not 3. Choice C (32 ounces) and choice D (64 ounces) are also incorrect as they do not accurately reflect the conversion of pints to ounces.
