Which is the largest fraction?
- A. 3/5
- B. 4/25
- C. 4/19
- D. 3/15
Correct Answer: A
Rationale: To determine the largest fraction, we need to compare the decimal equivalents of each fraction. Converting the fractions to decimals, we get: 3/5 = 0.6, 4/25 = 0.16, 4/19 ≈ 0.2105, 3/15 = 0.2. Comparing these decimals, we see that 3/5 (0.6) is the largest fraction among the options provided. Therefore, the correct answer is A) 3/5.

How many ounces are in 8 1/4 pints?
- A. 128 oz
- B. 2.25 oz
- C. 132 oz
- D. 136 oz
Correct Answer: C
Rationale: To convert pints to ounces, remember that 1 pint equals 16 fluid ounces. Therefore, 8 pints would be 8 x 16 = 128 ounces. Adding 1/4 pint (4 ounces) to 128 gives a total of 132 ounces in 8 1/4 pints. To calculate the total ounces, you add the ounces equivalent of the whole number of pints (8 pints = 8 x 16 = 128 ounces) to the ounces of the additional 1/4 pint, which is 4 ounces. Thus, 128 + 4 = 132 ounces in total for 8 1/4 pints.
Ratio and Proportion: 3 : 10 :: 12 : X
- A. X = 3.6
- B. X = 40
- C. X = 0.27
- D. X = 2.5
Correct Answer: B
Rationale: To solve this proportion, set up the equation: 3/10 = 12/X. Cross-multiply to get 3X = 120. Dividing both sides by 3 gives X = 40. Therefore, the correct answer is B. X equals 40 to maintain the proportional relationship. The ratio 3:10 is equivalent to the ratio 12:40, hence X equals 40.
If a die is rolled, what is the probability of getting an odd number?
- A. 50%
- B. 75%
- C. 16.70%
- D. 33%
Correct Answer: A
Rationale: When a fair six-sided die is rolled, there are 3 odd numbers (1, 3, 5) out of a total of 6 possible outcomes (1, 2, 3, 4, 5, 6). The probability of rolling an odd number is calculated by taking the number of favorable outcomes (3) divided by the total number of outcomes (6), which simplifies to 3/6 or 1/2, equivalent to 50%. Therefore, the correct answer is 50%. This means that when rolling a fair six-sided die, there is a 50% chance of getting an odd number.
What is the result of the subtraction: 28.19 - 9 = ?
- A. 28.1
- B. 18.19
- C. 27.29
- D. 19.19
Correct Answer: D
Rationale: To find the result of 28.19 - 9, align the decimal points and subtract each place value accordingly. Subtracting 9 from 28.19 results in 19.19. In this calculation, when subtracting 9 from 19 in the tenths place, 1 remains in the tenths place. Subtracting 0 from 8 in the ones place gives 8. Therefore, the correct answer is 19.19. It's crucial to maintain the alignment of decimal points while performing arithmetic operations involving decimals to ensure accuracy.
Convert 2100 to standard time =
- A. 9:00 PM
- B. 2:00 AM
- C. 2:00 PM
- D. 12:00 PM
Correct Answer: A
Rationale: To convert military time to standard time, subtract 12 hours if the time is after 12:00 PM. In this case, 2100 - 1200 = 900, which is equivalent to 9:00 PM in standard time notation. Remember that military time uses a 24-hour clock, where 2100 hours is equivalent to 9:00 PM in standard time format. Therefore, the correct answer is 9:00 PM.
