1. What is the result of (6.4)(2.8) ÷ 0.4? Which of the following is correct?

• A. 16.62
• B. 17.92
• C. 41.55
• D. 44.8

Correct answer: D

Rationale: To simplify the expression, first multiply 6.4 by 2.8 to get 17.92. Then, divide the result by 0.4 to find the final answer. Therefore, (6.4)(2.8) ÷ 0.4 equals 44.8. Choices A, B, and C are incorrect because they do not represent the correct result of the given expression.

2. A closet is filled with red, blue, and green shirts. If 2/5 of the shirts are green and 1/3 are red, what fraction of the shirts are blue?

• A. 4/15
• B. 1/5
• C. 7/15
• D. 1/2

Correct answer: C

Rationale: To find the fraction of blue shirts, subtract the fractions of green and red shirts from 1. Green shirts are 2/5 and red shirts are 1/3, which sum up to 11/15. Therefore, blue shirts would be 1 - 11/15 = 4/15. So, the correct answer is 4/15. Choice A (4/15) is incorrect as it represents the overall fraction of green shirts. Choice B (1/5) is incorrect as it does not account for the fractions of green and red shirts. Choice D (1/2) is incorrect as it does not consider the given fractions of green and red shirts.

3. After a long, exhausting hike, Stephanie went home and fell asleep on the couch, which she had done many times before. Which comma should be removed in the sentence above?

• A. The comma after the word 'long'
• B. The comma after the word 'hike'
• C. The comma after the word 'home'
• D. The comma after the word 'couch'

Correct answer: C

Rationale: The comma after 'home' is unnecessary and should be removed. In this sentence, 'and' is joining two independent clauses, which doesn't require a comma before it. Choices A, B, and D are incorrect because they are correctly placed commas within the sentence.

4. Which of the following sentences correctly uses a transition word?

• A. Gilda is a hardworking student; therefore, she earned a good grade on her essay.
• B. Gilda is a hardworking student; therefore she earned a good grade on her essay.
• C. Gilda is a hardworking student: therefore, she earned a good grade on her essay.
• D. Gilda is a hardworking student and therefore she earned a good grade on her essay.

Correct answer: A

Rationale: Choice A is the correct answer. 'Therefore' is correctly used as a transition word with proper punctuation in this sentence. In a compound sentence like this, a semicolon is used before the transition word to connect two independent clauses. Choice B is incorrect because it lacks the necessary punctuation to separate the independent clauses. Choice C is incorrect as a colon is not typically used before a transition word in this context. Choice D is incorrect because 'and' does not function as a transition word in this sentence.

5. Which of the following is a strong base commonly used in cleaning products?

• A. Sodium hydroxide (NaOH)
• B. Ammonium hydroxide (NHâ‚„OH)
• C. Calcium hydroxide (Ca(OH)â‚‚)
• D. Potassium hydroxide (KOH)

Correct answer: A

Rationale: Sodium hydroxide (NaOH) is a strong base commonly used in cleaning products due to its effectiveness in breaking down grease and fats. It is known for its corrosive properties and is commonly found in drain cleaners and oven cleaners. While ammonium hydroxide, calcium hydroxide, and potassium hydroxide are also bases, they are not as strong as sodium hydroxide and are not as commonly used in cleaning products. Ammonium hydroxide is more commonly found in household cleaning products for its disinfectant properties, calcium hydroxide is used in agriculture and construction, and potassium hydroxide is often used in industries like soap manufacturing and biodiesel production.
