TEAS Practice Test Math Questions
Question 1 of 5
Simplify the expression below. Which of the following is correct? 3.45 * 0.53
Correct Answer: A
Rationale: To simplify 3.45 * 0.53, multiply the numbers together: 3.45 * 0.53 = 1.8285 (Answer A). This is correct because when multiplying decimals, you multiply as if they were whole numbers and then place the decimal point in the answer based on the total number of decimal places in the factors. Summary of other choices: B: 18.285 - Incorrect as it is the result of adding the two numbers. C: 0.18285 - Incorrect as it is the result of placing the decimal point incorrectly. D: 182.85 - Incorrect as it is the result of ignoring the decimal places in the factors.
Question 2 of 5
A recipe calls for 5.5 teaspoons of vanilla. 1 teaspoon equals approximately 4.93 mL. Which of the following is the correct amount of vanilla in mL?
Correct Answer: D
Rationale: To find the correct amount of vanilla in mL, first, multiply 5.5 (teaspoons) by 4.93 (mL per teaspoon) to get 27.115 mL. Then round to the nearest whole number, giving 27 mL. Therefore, choice D is correct. Choices A, B, and C are incorrect as they do not result from the correct conversion calculation.
Question 3 of 5
Which of the following is the correct decimal placement for the product of 1.6 * 0.93?
Correct Answer: C
Rationale: To find the product of 1.6 and 0.93, we multiply the two numbers as usual: 1.6 * 0.93 = 1.488. The correct decimal placement for the product is C (1.488) because when multiplying decimal numbers, the total number of decimal places in the product should be equal to the sum of decimal places in the numbers being multiplied. In this case, 1.6 has one decimal place and 0.93 has two decimal places, totaling three decimal places. Therefore, the correct answer is 1.488, as it has three decimal places. Explanation for other choices: A: 14.88 - Incorrect as it has an extra decimal place. B: 0.1488 - Incorrect as it has one less decimal place. D: 0.001488 - Incorrect as it has more decimal places than the product of 1.6 * 0.93.
Question 4 of 5
Elevation above sea level and temperature are negatively correlated variables. Which of the following statements describes the relationship between the variables?
Correct Answer: C
Rationale: The correct answer is C: As elevation increases, temperature decreases. This is because of the negative correlation between elevation and temperature. As elevation increases (going higher above sea level), the temperature tends to decrease due to various factors like lower air pressure and thinner atmosphere. This relationship is observed in mountains where higher elevations have colder temperatures. Explanation of incorrect choices: A: As elevation decreases, temperature remains the same - Incorrect because the relationship is negative correlation, not no correlation. B: As elevation decreases, temperature decreases - Incorrect because the negative correlation implies that as elevation decreases, temperature would increase. D: As elevation increases, temperature increases - Incorrect because the negative correlation indicates that as elevation increases, temperature decreases.
Question 5 of 5
Which of the following weights is equivalent to 3.193 kilograms?
Correct Answer: B
Rationale: To convert kilograms to grams, we multiply by 1000 since 1 kg = 1000 grams. Therefore, 3.193 kg * 1000 = 3193 grams. Choice B, 3,193 grams, is the correct equivalent weight. Choices A, C, and D are incorrect as they do not correctly convert kilograms to grams. Choice A is way too large, choice C is too small, and choice D is significantly smaller than the original weight.
