1. Multiply: 3/4 Ã— 1/3.

A. 1/4
B. 1/3
C. 3/5
D. 3/8

Correct answer: A

Rationale: To multiply fractions, multiply the numerators together and the denominators together. In this case, 3/4 Ã— 1/3 = (3 Ã— 1) / (4 Ã— 3) = 3/12 = 1/4. Therefore, the correct answer is A: 1/4. Choices B (1/3), C (3/5), and D (3/8) are incorrect because they do not result from the correct multiplication of the given fractions.

2. Convert the percentage to a decimal: 38% =

A. 0.38
B. 3.8
C. 0.038
D. 38.0

Correct answer: A

Rationale: To convert a percentage to a decimal, you divide by 100. In this case, 38% divided by 100 equals 0.38. Moving the decimal point two places to the left converts the percentage to a decimal. Choice B is incorrect because it incorrectly moves the decimal point one place to the left. Choice C is incorrect as it moves the decimal point three places to the left. Choice D is incorrect as it does not convert the percentage to a decimal.

3. A cake recipe calls for 2Â½ cups of flour. How many cups are needed to make 6 cakes?

A. 12.5 cups
B. 13 cups
C. 14 cups
D. 15 cups

Correct answer: D

Rationale: To make one cake, you need 2Â½ cups of flour. To make 6 cakes, you would need 6 times the amount of flour for one cake, which is 2Â½ x 6 = 15 cups. Therefore, the correct answer is 15 cups. Choices A, B, and C are incorrect as they do not correctly calculate the total amount of flour needed for 6 cakes.

4. A worker's schedule is written in military time, and shows their shift is from 1500 to 0100. When will they get off work?

A. A little bit after midnight
B. 1:00 AM
C. 3:00 AM
D. 12:30 AM

Correct answer: B

Rationale: When converting military time, 0100 actually corresponds to 1:00 AM the next day. Choice A is incorrect as 'a little bit after midnight' is vague and not a specific time. Choice C is incorrect as it is after the worker's shift ends. Choice D is incorrect as it is before the worker's shift ends.
