How many fluid ounces are in 2 1/2 gallons?
- A. 300 oz
- B. 3,200 oz
- C. 320 oz
- D. 51.2 oz
Correct Answer: C
Rationale: To convert gallons to fluid ounces, we know that 1 gallon is equal to 128 fluid ounces. Therefore, to find out how many fluid ounces are in 2 1/2 gallons, we multiply 2.5 (2 1/2) by 128.
2.5 * 128 = 320
So, there are 320 fluid ounces in 2 1/2 gallons.
Rationale:
A: 300 oz is incorrect because it is less than the correct answer of 320 oz.
B: 3,200 oz is incorrect as it is too large for the amount of 2 1/2 gallons.
C: 320 oz is correct as calculated.
D: 51.2 oz is incorrect as it does not accurately represent the conversion of 2 1/2 gallons to fluid ounces.

Add: 5 1/3 + 3 1/2 =
- A. 8 2/6
- B. 9 1/4
- C. 8 2/5
- D. 8 5/6
Correct Answer: D
Rationale: To solve this problem, first convert the mixed numbers to improper fractions. 5 1/3 is equal to 16/3, and 3 1/2 is equal to 7/2. Next, find a common denominator, which in this case is 6. Convert 16/3 to 32/6 and 7/2 to 21/6. Add these fractions together: 32/6 + 21/6 = 53/6. Finally, simplify 53/6 to the mixed number 8 5/6. Therefore, the correct answer is D) 8 5/6.
Convert 0.60 to a ratio in simplest form.
- A. 3:5
- B. 2:50
- C. 2:6
- D. 1:6
Correct Answer: A
Rationale: To convert 0.60 to a ratio, start by expressing it as a fraction: 0.60 = 60/100. Then simplify the fraction by dividing both the numerator and denominator by their greatest common factor, which is 20 in this case. Dividing 60 by 20 gives 3, and dividing 100 by 20 gives 5. Therefore, the simplified fraction is 3/5, which translates to the ratio 3:5 in simplest form.
A dairy farmer wants to measure the milk production of his cows. He determines that the herd has produced a total of 250 gallons of milk this morning. How many quarts is this? (Enter numeric value only.)
- A. 500
- B. 750
- C. 1000
- D. 1250
Correct Answer: C
Rationale: The correct answer is C: 1000 quarts. To convert gallons to quarts, you need to know that 1 gallon is equal to 4 quarts. Therefore, to convert 250 gallons to quarts, you would multiply 250 by 4, which equals 1000 quarts. Choice A (500 quarts), B (750 quarts), and D (1250 quarts) are incorrect because they do not correctly convert the given amount of gallons to quarts. Be sure to always remember the conversion factor of 1 gallon to 4 quarts when solving such conversion problems.
Round to the nearest whole number: 4748 — 12 =
- A. 372
- B. 384
- C. 396
- D. 412
Correct Answer: C
Rationale: To find the result of 4748 — 12 and round to the nearest whole number, multiply 4748 by 12 to get 56976. When considering rounding to the nearest whole number, 56976 is closest to 57000. Since 56976 is closer to 57000 than to 56000, the rounded answer is 57000. Therefore, the correct rounded answer is 57000, which corresponds to 396 in the given choices.
What is the sum of 6 + 12.55 + 5.022?
- A. 18.55
- B. 23.572
- C. 30.572
- D. 16.575
Correct Answer: B
Rationale: To find the sum of 6, 12.55, and 5.022, add them together. 6 + 12.55 equals 18.55. Adding 5.022 to 18.55 gives a total of 23.572. Therefore, the correct answer is 23.572. The sum of these numbers is calculated by adding the individual values together while maintaining the decimal points in their respective places to get the correct total. It's essential to be precise with decimal numbers to ensure the accuracy of the final sum.
