1. Lights out on the base is at 10:30 P.M. What would that be in military time?
- A. 1030
- B. 1300
- C. 1230
- D. 2230
Correct answer: D
Rationale: In military time, the time of 10:30 P.M. is represented as 2230. Military time follows a 24-hour clock system where hours are not converted to a 12-hour clock. Each hour is represented from 00 to 23. Therefore, 10:30 P.M. in military time is 2230. Choice A, 1030, is incorrect as it represents 10:30 A.M. Choice B, 1300, stands for 1:00 P.M., and Choice C, 1230, is equivalent to 12:30 P.M. Hence, the correct answer is D.
2. What is the result of subtracting 4.7 from 9.5?
- A. 4.8
- B. 4.9
- C. 4.6
- D. 4.7
Correct answer: A
Rationale: The correct subtraction is 9.5 - 4.7 = 4.8. Therefore, the correct answer is 4.8. Choice B (4.9) is incorrect because 9.5 - 4.7 is not equal to 4.9. Choice C (4.6) is incorrect as it is not the result of subtracting 4.7 from 9.5. Choice D (4.7) is the number being subtracted and not the result of the subtraction.
3. How many ounces are in 4.5 quarts?
- A. 120 ounces
- B. 120 ounces
- C. 144 ounces
- D. 128 ounces
Correct answer: C
Rationale: There are 32 ounces in a quart, so to find out how many ounces are in 4.5 quarts, you need to multiply 4.5 by 32. 4.5 quarts * 32 ounces/quart = 144 ounces. Therefore, the correct answer is 144 ounces. Choices A, B, and D are incorrect because they do not correctly calculate the conversion from quarts to ounces.
4. 5 1\3 + 3 1\2.
- A. 8 5/6
- B. 9
- C. 7
- D. 8
Correct answer: A
Rationale: 5 1\3 + 3 1\2 equals 8 5\6.
5. How many gallons are in 16 quarts?
- A. 1 gallon
- B. 8 gallons
- C. 4 gallons
- D. 4.5 gallons
Correct answer: C
Rationale: To convert quarts to gallons, remember that 1 gallon equals 4 quarts. Therefore, 16 quarts ÷ 4 quarts/gallon = 4 gallons. The correct answer is 4 gallons because each gallon contains 4 quarts. Choice A (1 gallon) is incorrect because 1 gallon is equal to 4 quarts, not 16 quarts. Choice B (8 gallons) is incorrect as it miscalculates the conversion. Choice D (4.5 gallons) is incorrect because it doesn't align with the conversion rate of 4 quarts per gallon.
