Math Practice TEAS Test
1. In a fraction, which number is the numerator and which is the denominator?
- A. Numerator: top, Denominator: bottom
- B. Numerator: bottom, Denominator: top
- C. Numerator: left, Denominator: right
- D. Numerator: right, Denominator: left
Correct answer: A
Rationale: The correct answer is A: 'Numerator: top, Denominator: bottom.' In a fraction, the numerator is the top number, representing the part of the whole being considered, while the denominator is the bottom number, indicating the total number of equal parts into which the whole is divided. Choices B, C, and D are incorrect because they provide inaccurate descriptions of the numerator and denominator positions in a fraction.
2. What is the role of bile in digestion?
- A. To break down carbohydrates
- B. To emulsify fats
- C. To neutralize stomach acid
- D. To absorb proteins
Correct answer: B
Rationale: Bile emulsifies fats, breaking them down into smaller droplets for easier digestion.
3. What is the most effective way to rewrite the following sentence: She is saying that some of the students are wearing to school is being distracting and inappropriate?
- A. Some of the outfits students wear to school, she is saying, are distracting and not appropriate.
- B. The outfits are distracting and inappropriate, she says, that students wear to school.
- C. She says that some of the outfits that students wear to school are distracting and inappropriate.
- D. She says that it is distracting and inappropriate that students wear outfits to school.
Correct answer: C
Rationale: The most effective way to rewrite the sentence is, 'She says that some of the outfits that students wear to school are distracting and inappropriate.' This choice corrects the sentence structure by placing the subject ('Some of the outfits') before the verb ('are'), making it clearer and more grammatically correct. Choice A is incorrect as it places the subject after the verb, which disrupts the sentence structure. Choice B is incorrect as it changes the meaning of the sentence by placing the verb before the subject. Choice D is incorrect as it creates a confusing sentence structure by using 'that' redundantly.
4. Which of the following organs is responsible for filtering waste from the blood?
- A. Liver
- B. Kidneys
- C. Pancreas
- D. Heart
Correct answer: B
Rationale: The correct answer is B: Kidneys. The kidneys play a vital role in filtering waste from the blood, regulating fluid and electrolyte balance in the body. The liver is involved in detoxification and metabolism, while the pancreas aids in digestion and blood sugar regulation. The heart is responsible for pumping blood throughout the body and does not directly filter waste from the blood.
5. Which of the following is LEAST likely to be found in a human cell's genes?
- A. Sequences of amino acids to be transcribed into mRNA
- B. Lethal recessive traits like sickle cell anemia
- C. Mutated DNA
- D. DNA that codes for proteins the cell doesn't use
Correct answer: D
Rationale: Human cells typically contain genes that code for proteins necessary for the cell's functions. DNA that codes for proteins the cell doesn't use would be an inefficient use of the cell's resources. Therefore, it is less likely to be found in a human cell's genes. Options A, B, and C are more commonly associated with genes found in human cells. Choice A refers to the genetic information needed for protein synthesis, while choice B involves traits that can be present in the gene pool. Mutated DNA (choice C) can also be found in human cells as a result of genetic alterations. However, DNA that codes for proteins not utilized by the cell would be redundant and not typically retained in the genome.
