TEAS Math Practice Test Questions
Question 1 of 5
What is the perimeter of a rectangle with a length of 7 cm and a width of 3 cm?
Correct Answer: D
Rationale:
To find the perimeter of a rectangle, you add the lengths of all its sides. In this case, the formula for the perimeter of a rectangle is 2*(length + width). Substituting the given values, we get: 2*(7 cm + 3 cm) = 2*(10 cm) = 20 cm.
Therefore, the correct answer is 20 cm.
Choice A (21 cm) is incorrect because it is the sum of the individual sides rather than the perimeter.
Choice B (10 cm) is incorrect because it only represents one side of the rectangle.
Choice C (14 cm) is incorrect as it is not the total perimeter of the rectangle.
Question 2 of 5
Five of six numbers have a sum of 25. The average of all six numbers is 6. What is the sixth number?
Correct Answer: C
Rationale:
To find the sum of all six numbers, we multiply the average (6) by the total numbers (6), which equals 36. Since the sum of five numbers is 25, the sixth number can be found by subtracting the sum of five numbers from the total sum: 36 - 25 = 11.
Therefore, the sixth number is 11.
Choice A, 8, is incorrect because adding 8 to the sum of five numbers (25) would result in a total greater than the correct sum of all six numbers (36).
Choice B, 10, is incorrect because adding 10 to the sum of five numbers (25) would also result in a total greater than the correct sum of all six numbers (36).
Choice D, 12, is incorrect because adding 12 to the sum of five numbers (25) would exceed the correct sum of all six numbers (36).
Question 3 of 5

Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 4 of 5
Jessica buys 10 cans of paint. Red paint costs $1 per can, and blue paint costs $2 per can. In total, she spends $16. How many red cans did she buy?
Correct Answer: C
Rationale: Let r be the number of red cans and b be the number of blue cans. The total cans equation is r + b = 10. The total cost equation is r + 2b = 16. By solving these equations simultaneously, we find r = 4.
Therefore, Jessica bought 4 red cans.
Choice A, 2 red cans, is incorrect because it does not satisfy the total cans or total cost condition.
Choices B and D are also incorrect as they do not fulfill both conditions simultaneously.
Question 5 of 5
Which operation should be completed first in the expression 8 + 5 * 3?
Correct Answer: A
Rationale: The correct answer is 'Multiplication.' In the expression 8 + 5 * 3, according to the order of operations (PEMDAS), multiplication should be done before addition. PEMDAS stands for Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right).
Therefore, the multiplication operation should be completed first, making 5 * 3 equal to 15, and then the addition operation should be conducted to get the final result of 8 + 15, which equals 23.
Choices B, C, and D are incorrect because in this expression, multiplication takes precedence over addition, division, and subtraction according to the order of operations.
