TEAS Practice Math Test

Correct Answer: C

Rationale: To determine the order from least to greatest, convert all fractions to decimal equivalents. -2 3/4 = -2.75 -2 7/8 = -2.875 -1/5 = -0.2 1/8 = 0.125 2/5 = 0.4 Now arrange them in ascending order: -2.875, -2.75, -0.2, 0.125, 0.4 Therefore, the correct order from least to greatest is -2 7/8, -2 3/4, -1/5, 1/8, 2/5 (Option C). Other choices are incorrect as they do not follow the correct order of the numbers when arranged from least to greatest.

Correct Answer: A

Rationale: The correct answer is A: $600. The first step is to calculate the amount saved after paying rent and utilities. Since she uses 2/5 for rent and utilities, she saves 3/5 of her monthly contribution. Then, she saves half of this amount for incidental expenditures, which means she spends the other half on medical supplies. Therefore, she spends 1/4 of her monthly contribution on medical supplies. If we let her monthly contribution be x, then 1/4 of x equals $600. Therefore, the correct answer is $600. Choices B, C, and D are incorrect because they do not align with the calculations based on the given information.

Correct Answer: A

Rationale: To calculate the total cost, first multiply the daily rental cost by the number of days ($50 * 3 = $150). Then, multiply the cost per mile by the total miles driven ($0.25 * 120 = $30). Add these two amounts ($150 + $30 = $180). Therefore, the correct total cost is $180. Among the choices, only option A ($156) is incorrect as it does not match the calculated total cost. Option B ($190) is incorrect as it is higher than the correct total cost. Option C ($165) is incorrect as it is also higher than the correct total cost. Option D ($210) is incorrect as it is higher than the correct total cost.

Correct Answer: B

Rationale: The best estimate of the total number of pounds of potatoes on the farmer's trailer can be calculated by finding the average weight per bag and then multiplying it by the total number of bags. Since each bag contains between 23 to 27 pounds, we can estimate the average weight per bag to be around 25 pounds. With 150 bags, the total weight would be approximately 150 bags * 25 pounds per bag = 3,750 pounds. Therefore, the best estimate is 3,700 pounds (Choice B). Choice A (3,000 pounds) is too low as it assumes the lowest possible weight per bag consistently. Choice C (4,100 pounds) is too high as it assumes the highest possible weight per bag consistently. Choice D (5,000 pounds) is also too high and overestimates the total weight based on the given information.
