1. A woman received a bottle of perfume as a present. The bottle contains 3/4 oz of perfume. How many milliliters is this?

• A. 25 mL
• B. 22.5 mL
• C. 15 mL
• D. 20 mL

Correct answer: B

Rationale: To convert ounces to milliliters, multiply the number of ounces by 29.5735. 3/4 oz × 29.5735 ≈ 22.5 mL. Therefore, the correct answer is 22.5 mL. Choice A (25 mL) is incorrect as it does not result from the correct conversion. Choices C (15 mL) and D (20 mL) are also incorrect conversions.

2. A doctor prescribes 150 milligrams of medication to be taken orally every 12 hours. How many grams should the patient take per dose?

• A. 0.015 grams
• B. 0.15 grams
• C. 1.5 grams
• D. 15 grams

Correct answer: B

Rationale: Rationale: 1. Convert milligrams to grams: 150 milligrams = 150/1000 = 0.15 grams. Therefore, the patient should take 0.15 grams per dose. Choice A (0.015 grams) is incorrect as the decimal point was misplaced, leading to a value that is too small. Choice C (1.5 grams) is incorrect as it represents 10 times the correct value. Choice D (15 grams) is incorrect as it represents 100 times the correct value. The correct conversion from milligrams to grams is 0.15 grams.

3. Subtract 28 3/4 - 5 5/6.

• A. 22 & 11/12
• B. 23 & 1/2
• C. 34 & 1/12
• D. 22 & 2/3

Correct answer: A

Rationale: To subtract mixed numbers, find a common denominator. Convert 28 3/4 to 28 9/12. Then, subtract 5 5/6 from 28 9/12 to get 22 11/12. Therefore, 28 3/4 - 5 5/6 = 22 & 11/12, which matches choice A. Choices B, C, and D are incorrect because they do not reflect the correct subtraction result after finding the common denominator and performing the subtraction.

4. Bill has 2.5 vacation days left for the rest of the year and 1.25 sick days left. If Bill uses all of his sick days and his vacation days, how many days will he have off work?

• A. 1 day
• B. 3 days
• C. 2 days
• D. 4 days

Correct answer: D

Rationale: To find the total number of days Bill will have off, add his vacation days and sick days together. Bill has 2.5 vacation days and 1.25 sick days: 2.5 + 1.25 = 3.75 days When rounding to the nearest whole number, 3.75 rounds up to 4. Therefore, Bill will have 4 days off work.

5. What is the area of a rectangular room with a length of 12 meters and a width of 10 meters?

• A. 120 square meters
• B. 130 square meters
• C. 140 square meters
• D. 100 square meters

Correct answer: A

Rationale: The correct answer is A: 120 square meters. To find the area of a rectangle, you multiply its length by its width. In this case, the length is 12 meters and the width is 10 meters. Therefore, the area of the room is 12m * 10m = 120 square meters. Choices B, C, and D are incorrect as they do not correctly calculate the area of the room based on its dimensions.
