TEAS Math Practice Test

Correct Answer: B

Rationale: Correct Answer: B Rationale: To find 40% of N, you can multiply N by 0.4 (equivalent to 40/100). Therefore, the correct way is 0.4N. Option B (N/40) is incorrect because dividing N by 40 does not give 40% of N. Option A (0.4N) is correct. Option C (2/5 N) is equivalent to 40%. Option D (40N/100) simplifies to 0.4N, which is correct.

Option D (40N/100) simplifies to 0.4N, which is correct.

Correct Answer: C

Rationale: The number -4 is classified as real, rational, and integer. 1. Real: -4 is a real number as it exists on the number line. 2. Rational: -4 can be expressed as -4/1, which is a ratio of two integers. 3. Integer: -4 is a whole number that includes negative numbers. Therefore, the correct answer is C. Summary: A: Incorrect, as it includes "natural," which does not apply to negative numbers. B: Incorrect, as it includes "natural," which is only positive integers. D: Incorrect, as -4 is rational, not irrational.

Correct Answer: B

Rationale: To convert 1.25 to a fraction, we note that the decimal has two decimal places. To convert it to a fraction, we write 1.25 as 125/100. Simplifying by dividing both numerator and denominator by 25, we get 5/4. Therefore, the correct answer is B: 5/4. A: 1 1/4 is the mixed number form of 5/4. C: 4/5 is the reciprocal of the correct answer. D: 25/20 is not simplified; it should be reduced to 5/4.

Correct Answer: D

Rationale: Correct Answer: D (1 apple) Rationale: 1. Xavier starts with 20 apples. 2. He gives half to Emma, leaving him with 10 apples. 3. He gives 6 apples to Jim, leaving him with 4 apples. 4. He uses 3/4 of his remaining 4 apples for the pie, leaving him with 1 apple. Summary: - Choice A (4 apples) is incorrect because Xavier uses 3/4 of his remaining apples for the pie. - Choice B (6 apples) is incorrect because Xavier gives 6 apples to Jim. - Choice C (2 apples) is incorrect because Xavier uses 3/4 of his remaining apples for the pie.
