1. A teacher's aide must convert the directions from quarts to liters. The directions say to dilute the contents of a package in 3 quarts of water. How many liters should be used?

A. 2.8 liters
B. 3.5 liters
C. 2.5 liters
D. 4.0 liters

Correct answer: A

Rationale: To convert quarts to liters, you can multiply the number of quarts by 0.946353. In this case, 3 quarts is approximately 2.8 liters. Therefore, the correct answer is 2.8 liters. Choices B, C, and D are incorrect as they do not reflect the accurate conversion from quarts to liters.

2. Out of a total of 50 homes, she sold 11. What percentage of the homes did she sell?

A. 16%
B. 18%
C. 22%
D. 24%

Correct answer: C

Rationale: To find the percentage of homes she sold, divide the number of homes she sold (11) by the total number of homes (50), then multiply by 100. (11 / 50) * 100 = 22%. Therefore, she sold 22% of the homes. Choice A (16%) is incorrect because it is less than the correct percentage. Choice B (18%) is also less than the correct percentage. Choice D (24%) is greater than the correct percentage of homes she sold.

3. What number is 80 125% of?

A. 48
B. 64
C. 68
D. 78

Correct answer: B

Rationale: To find the number that 80 is 125% of, we can set up the equation: x = 80 / 1.25. Solving this equation gives x = 64. Therefore, 80 is 125% of 64. Choice A (48) is incorrect because it is not the correct value that 80 is 125% of. Choice C (68) is incorrect as it is not the value that satisfies the given percentage relationship. Choice D (78) is incorrect as it does not match the calculation result.

4. Subtract 12 - 7 & 4\5.

A. 4 & 4\5
B. 5 & 4\5
C. 4 & 1\5
D. 5 & 1\5

Correct answer: C

Rationale: 12 - 7 & 4\5 equals 4 & 1\5.

5. What is 70% of 200?

A. 100
B. 100
C. 200
D. 140

Correct answer: D

Rationale: To find 70% of a number, you multiply the number by 0.70. Therefore, 70% of 200 is calculated as 0.7 × 200 = 140. Choices A, B, and C are incorrect as they do not represent the correct calculation for finding 70% of 200.
