Math Practice TEAS Test

Correct Answer: B

Rationale: To calculate the number of tanks needed, divide total miles by miles per gallon: 1,800 miles / 30 mpg = 60 gallons. Then, divide total gallons by tank capacity: 60 gallons / 12 gallons = 5 tanks. Therefore, Robert will need 5 tanks of gas for the trip. Summary: - Choice A (4 tanks) is incorrect because the correct calculation shows 5 tanks are needed. - Choice C (6 tanks) is incorrect as it overestimates the number of tanks required. - Choice D (7 tanks) is incorrect as it also overestimates the number of tanks needed based on the given information.

Correct Answer: C

Rationale: A rational number can be expressed as a fraction or a decimal. A fraction is a ratio of two integers, and a decimal can represent a rational number, such as 0.5 (which is 1/2). Hence, a rational number can be a fraction, decimal, or a whole number. Options A and D are incorrect because a rational number is not limited to being a whole number or cannot be a decimal. Option B is partially correct but doesn't cover the full scope of possibilities for rational numbers. Option C is the correct answer as it encompasses all the possible representations of a rational number.

Correct Answer: B

Rationale: The correct answer is B: Frequency. A histogram is preferred over a bar graph when displaying frequency distribution data, as it shows the frequency of values within intervals or bins. It is used to represent continuous data and helps visualize the distribution and shape of the data. Choice A is incorrect because bar graphs are typically used for comparing different categories. Choices C and D are incorrect because percentages and proportions are more suitable for other types of graphs like pie charts or stacked bar graphs.

Correct Answer: A

Correct Answer: B

Rationale: To convert liters to quarts, we use the conversion factor 1 liter = 1.06 quarts. Therefore, 1 liter is equal to 1.06 quarts. The correct answer is B. Choice A is incorrect as it states 1 quart is equal to 1 liter. Choice C is incorrect as it states 2 quarts are in 1 liter. Choice D is incorrect as it states 0.5 quarts are in 1 liter.
