TEAS Practice Test Math Questions
Question 1 of 5
What is an exponent?
Correct Answer: A
Rationale: An exponent is a number that indicates how many times a base number is multiplied by itself. The correct answer (A) accurately defines an exponent as a multiplier that shows how many times a number should be multiplied by itself. Choice B is incorrect as it describes a factor rather than an exponent. Choice C is incorrect as it defines a divisor, not an exponent. Choice D is incorrect as it specifically refers to the square of a number, which is not a general definition of an exponent.
Question 2 of 5
What is a quotient?
Correct Answer: A
Rationale: A quotient is the result of dividing one number by another. Choice A is correct because it accurately defines a quotient as the outcome of a division operation. Choice B is incorrect because it describes the result of multiplying two numbers, not dividing them. Choice C is incorrect because it refers to the remainder of a subtraction operation, not a division. Choice D is incorrect because it mentions the number remaining after a division, which is typically referred to as the remainder and not the quotient.
Question 3 of 5
What is an equivalent fraction?
Correct Answer: A
Rationale: An equivalent fraction is a fraction that may look different in terms of its numerator and denominator but still represents the same value or quantity. This means that when you simplify or expand a fraction, its value remains unchanged. Choice B and C are incorrect because equivalent fractions are not determined by being smaller or larger than another fraction; it is about representing the same quantity. Choice D is incorrect because equivalent fractions may have different numerators as long as the ratio between the numerator and denominator remains the same.
Question 4 of 5
A patient requires a 30% increase in the dosage of their medication. Their current dosage is 270 mg. What will their dosage be after the increase?
Correct Answer: D
Rationale: To calculate a 30% increase from the current dosage of 270 mg, first find 30% of 270, which is 81 mg. Add this 81 mg increase to the original dosage of 270 mg to get the new dosage, which is 351 mg (270 mg + 81 mg = 351 mg). Therefore, the correct answer is 351 mg. Choice A (81 mg) is incorrect because this value represents only the calculated 30% increase, not the total dosage after the increase. Choice B (270 mg) is the original dosage and does not account for the 30% increase. Choice C (300 mg) is close to the correct answer but does not consider the precise 30% increase calculation, leading to an incorrect total dosage.
Question 5 of 5
Based on their prescribing habits, a set of doctors was divided into three groups: 1/4 of the doctors were placed in Group X because they always prescribed medication. 1/3 of the doctors were placed in Group Y because they never prescribed medication. 1/6 of the doctors were placed in Group Z because they sometimes prescribed medication. Order the groups from largest to smallest, according to the number of doctors in each group.
Correct Answer: D
Rationale: In this question, it is essential to understand the fractions given for each group of doctors. Group X has 1/4 of the doctors, Group Y has 1/3, and Group Z has 1/6. To determine the largest group, we need to compare the fractions. 1/3 is greater than 1/4, so Group Y is larger than Group X. Similarly, 1/3 is greater than 1/6, so Group Y is also larger than Group Z. Therefore, the correct order is Group Y (largest), Group X, and Group Z (smallest). Option A (Group X, Group Y, Group Z) is incorrect because Group Y has more doctors than Group X. Option B (Group Z, Group Y, Group X) is incorrect because Group Y has more doctors than Group Z. Option C (Group Z, Group X, Group Y) is incorrect for the same reason. Understanding fractions and their relationships is crucial in math, as it helps in comparing and ordering quantities accurately. This question assesses the ability to interpret fractions and apply that understanding to solve a real-world scenario involving grouping and comparison.
