Correct Answer: B

Rationale: To find 2/3 of 60, multiply 60 by 2/3, which gives 40. Next, find 1/5 of 75 by multiplying 75 by 1/5, which equals 15. Adding 40 and 15 gives us 55. Therefore, the correct answer is B (55). Choice A (45) is incorrect as it only considers 2/3 of 60 without adding 1/5 of 75. Choices C (15) and D (50) also do not account for both parts of the equation.

Correct Answer: B

Rationale: To find the total number of games played, we divide the number of games won (72) by the percentage of games won (90%). This gives us 72 / 0.90 = 80 games played. Therefore, choice B is correct. Choice A (75) is incorrect because it does not account for the percentage of games won. Choice C (85) is incorrect as it overestimates the total number of games played. Choice D (100) is incorrect as it does not reflect the fact that the team won only 90% of the games played.

Correct Answer: A

Rationale: To add 9.43 and 11.3, align the decimal points and add the numbers as follows: 9.43 +11.30 ------- 20.73 Therefore, the correct answer is A: 20.73. The other choices are incorrect as they do not match the sum obtained through the addition process. B: 21.3 does not account for the decimal place in 9.43. C: 22 is the sum of the whole numbers without considering the decimal values. D: 19.5 is the sum if the decimal values are not accounted for.

Correct Answer: C

Rationale: To convert 5 gallons to quarts, we know that 1 gallon = 4 quarts. So, 5 gallons = 5 x 4 = 20 quarts. Since she needs quart jars, Jan will need to buy 20 quart jars to can her 5 gallons of homemade tomatoes. Choices A, B, and D are incorrect because they do not correctly convert gallons to quarts. Choice A (10) is half of the correct answer, choice B (15) is three-quarters, and choice D (25) is more than the actual amount needed.

Correct Answer: A

Rationale: To find the total days off work, we add Bill's remaining vacation days (5.5) and sick days (3.25). 5.5 + 3.25 = 8.75 Therefore, Bill will have 8.75 days off work if he uses all of his remaining vacation and sick days. Choice A (8.75) is correct because it accurately represents the total days off. Choices B, C, and D are incorrect as they do not correctly calculate the total days off based on the given information.
