Math Practice TEAS Test Questions
Question 1 of 5
How many centimeters in an inch? How many inches in a centimeter?
Correct Answer: A
Rationale: The correct conversion is: 1 inch = 2.54 centimeters and 1 centimeter = 0.393 inches.
Therefore, option A is correct. Option B is incorrect as the conversion is incorrect. Option C is incorrect as it does not match the correct conversion values. Option D is incorrect as the conversion values provided are inaccurate.
Question 2 of 5
Which unit of measurement is larger, inches or centimeters?
Correct Answer: A
Rationale: Inches are larger than centimeters. This is because one inch is equivalent to 2.54 centimeters.
Therefore, when comparing the two units, inches are greater in length than centimeters.
Choice B is incorrect as centimeters are smaller than inches.
Choice C is incorrect as inches and centimeters are not the same size.
Choice D is incorrect as the relationship between inches and centimeters is fixed, with inches being larger in general.
Question 3 of 5
When is a histogram preferred over a bar graph?
Correct Answer: B
Rationale: Histograms are specifically designed to display the frequency distribution of continuous data, showing the distribution of values over intervals or bins. On the other hand, bar graphs are used to compare different categories or discrete data points.
Therefore, the correct answer is B.
Choices A, C, and D are incorrect because histograms are not primarily used for comparing categories, percentages, or proportions, but rather for visualizing the distribution of frequencies within data intervals.
Question 4 of 5
A patient requires a 30% decrease in the dosage of their medication. Their current dosage is 340 mg. What will their dosage be after the decrease?
Correct Answer: B
Rationale:
To calculate a 30% decrease in 340 mg, you multiply 340 by 0.3, which equals 102 mg. Subtracting this from the current dosage gives 340 - 102 = 238 mg.
Therefore, the correct answer is 238 mg.
Choice A (70 mg) is incorrect because it represents a 70% decrease, not 30%.
Choice C (270 mg) is incorrect as it does not reflect the correct calculation for a 30% decrease.
Choice D (340 mg) is the initial dosage and not the reduced dosage after a 30% decrease.
Question 5 of 5
In Mrs. McConnell's classroom, there are 5 students with hazel eyes and 2 students with green eyes out of a total of 30 students. What percentage of the students have either hazel or green eyes?
Correct Answer: A
Rationale:
To calculate the percentage of students with either hazel or green eyes, add the number of students with hazel and green eyes (5 + 2 = 7) and divide by the total number of students (30): 7 · 30 ≈ 0.23 or 23%. The correct answer is A, 0.23, which represents 23% of the total students.
Choice B, 0.3, is incorrect as it corresponds to 30%, which is higher than the total number of students.
Choice C, 0.47, is incorrect as it represents 47%, which is also higher than the total number of students.
Choice D, 0.77, is incorrect as it corresponds to 77%, which is much higher than the total number of students.
