1. Add 7/8 + 9/10 + 6/5. Express the result as a mixed number.

• A. 3 & 39/40
• B. 3 & 22/23
• C. 22/23
• D. 2 & 39/40

Correct answer: A

Rationale: To add fractions, find a common denominator, which in this case is 40. Convert each fraction to have the common denominator: 7/8 = 35/40, 9/10 = 36/40, and 6/5 = 48/40. Add these fractions to get 119/40. Simplify this improper fraction to a mixed number, which is 3 & 39/40. Choice B and C are incorrect as they do not represent the sum of the fractions. Choice D is incorrect; the whole number part should be 3, not 2.

2. Which bone is shorter in the forearm?

• A. Humerus
• B. Radius
• C. Scapula
• D. Fibula

Correct answer: B

Rationale: The correct answer is B: Radius. The forearm consists of two long bones: the radius and the ulna. The radius is located on the thumb side of the forearm and is shorter than the ulna, which is on the pinky side. The humerus is the bone located in the upper arm, the scapula is the shoulder blade bone, and the fibula is a bone in the lower leg. Therefore, they are not the shorter bone in the forearm.

3. Which word is used incorrectly in the following sentence? She is already an adjunct at a college in Raleigh, the capital of North Carolina.

• A. already
• B. adjunct
• C. college
• D. capital

Correct answer: C

Rationale: The word 'college' is used incorrectly in the sentence. The correct term to use in this context would be 'capital,' not 'college.' 'Capital' refers to the city that serves as the seat of government, while 'college' refers to an educational institution. The sentence should read: 'She is already an adjunct at a capital in Raleigh, the capital of North Carolina.' Choices A, B, and D are all used appropriately in the sentence.

4. Subtract 2 5\8 - 7\8 and reduce.

• A. 1 & 5\8
• B. 1 & 1\4
• C. 1 & 6\8
• D. 1 & 3\4

Correct answer: A

Rationale: Subtract the fractions first: 2 5\8 - 7\8 = 1 & 5\8.

5. If fifty-six kilograms of a radioactive substance has a half-life of 12 days, how many days will it take the substance to decay naturally to only 7 kilograms?

• A. 8
• B. 12
• C. 36
• D. 48

Correct answer: C

Rationale: To decay from 56 kg to 7 kg, the substance needs to go through 3 half-lives (56 kg ÷ 2 ÷ 2 ÷ 2 = 7 kg). Since each half-life is 12 days, the total time required is 12 days per half-life x 3 half-lives = 36 days. Choice A is incorrect because it does not consider the concept of half-lives. Choice B is incorrect because it represents the duration of a single half-life, not the total time required for the decay. Choice D is incorrect as it does not account for the multiple half-lives needed for the substance to decay from 56 kg to 7 kg.
