TEAS Practice Test Math

Correct Answer: D

Rationale: To compare the values, convert them to the same format. Convert 2/11 to a decimal (0.1818), 13/3 to a decimal (4.33), and 6.25 remains unchanged. Now, it's clear that 6.25 is the greatest value as it is larger than both 0.1818 and 4.33. Option B (5.4) is also smaller than 6.25. Thus, the correct answer is D.

Correct Answer: A

Rationale: To find the least common denominator (LCD), we need to find the least common multiple (LCM) of the denominators. The denominators are 2, 3, and 5. The LCM of 2, 3, and 5 is 30, which is the smallest number that all three denominators divide into evenly. Therefore, the correct answer is A: 30. Choice B: 25 is not the correct answer because it is not divisible by 2, 3, and 5. Choice C: 7 is not the correct answer because it is not divisible by 2, 3, and 5. Choice D: 19 is not the correct answer because it is not divisible by 2, 3, and 5.

Correct Answer: C

Rationale: To calculate the 16% gratuity on a $58.60 bill, you multiply the bill amount by 0.16 (16%). $58.60 x 0.16 = $9.38. Therefore, the estimated gratuity is $9.38 (Choice C). Incorrect Answers: A: $8.48 - Incorrect, this is not the correct calculation for a 16% gratuity on $58.60. B: $6.40 - Incorrect, this is the calculation for a 11% gratuity on $58.60. D: $7.00 - Incorrect, this is the calculation for a 12% gratuity on $58.60.

Correct Answer: A

Rationale: The correct answer is A because an integer is defined as a whole number that can be positive, negative, or zero. Integers do not include fractions or decimals (eliminating choices B and C) or percentages (eliminating choice D). Integers are the set of numbers {..., -3, -2, -1, 0, 1, 2, 3, ...} and do not include numbers with decimal points or fractions. Therefore, choice A is the only option that accurately describes what defines an integer.

Correct Answer: C

Rationale: To find the amount of sugar needed for 0.625 of the recipe, you multiply 0.375 (original amount) by 0.625 (desired portion). 0.375 x 0.625 = 0.234375 cups. Therefore, you should use 0.234375 cups of sugar. Choice A is incorrect as it adds the original and desired portions. Choice B is close but not the correct calculation. Choice D is way off, likely a miscalculation.
