TEAS Practice Test Math

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.

Correct Answer: A

Rationale: The correct answer is A: 0.75 hectares. To calculate the area of the soccer field in square meters, you multiply the length by the width (100m x 75m = 7500 square meters). To convert this to hectares, you divide by 10,000 (7500 ÷ 10,000 = 0.75 hectares). Choice B (7.5 hectares) is incorrect because it is 10 times the correct answer. Choice C (7,500 hectares) is incorrect because it is 1,000 times the correct answer. Choice D (75,000,000 hectares) is incorrect because it is 100,000 times the correct answer.

Correct Answer: A

Rationale: To calculate the number of months, we first subtract the down payment from the total cost to get the remaining balance: $1570 - $400 = $1170. Then, we divide the remaining balance by the monthly payment to determine the number of months: $1170 / $100 = 11.7 months. Since we cannot have partial months in this case, we round up to the nearest whole number, giving us 12 months. Therefore, the correct answer is A (12 months). Choice B (16 months) is too high, Choices C (15 months) and D (11 months) are too low based on the calculations.

Correct Answer: A

Rationale: To convert yards to feet, you multiply by 3 because there are 3 feet in 1 yard. To convert feet to yards, you divide by 3. So, the correct answer is A. For the other choices, B, C, and D, the conversion factors are incorrect and do not match the actual relationship between yards and feet. B and D have incorrect multiplication factors, while C has an incorrect multiplication factor and division factor.

Correct Answer: B

Rationale: To find the number of students in the respiratory care program, we need to calculate the percentage of students in that program based on the pie chart. The respiratory care program occupies 19% of the pie chart. 19% of 800 students is 0.19 * 800 = 152. Therefore, the correct answer is B: 152. Choice A (336) is incorrect as it represents the percentage of students in a different program, not respiratory care. Choice C (144) and Choice D (168) are also incorrect as they do not correspond to the percentage allocated for the respiratory care program in the pie chart.
