TEAS Math Questions Questions
Question 1 of 5
There are 20 mg of acetaminophen in concentrated infant drops. If the proper dosage for a four-year-old child is 240 mg, how many milliliters should the child receive?
Correct Answer: C
Rationale: To calculate the correct dosage for the child, we divide the required dosage (240 mg) by the concentration of acetaminophen in the drops (20 mg/mL). This gives us 12 mL as the correct amount. Therefore, the child should receive 2.4 mL (12 mL divided by 5) of concentrated infant drops. Option C is correct because it accurately represents the calculated dosage. Options A, B, and D are incorrect as they do not reflect the correct calculation based on the concentration and required dosage.

Question 3 of 5
If you have a rectangle with a width of 5 inches and a length of 10 inches and scale it by a factor of 2, what will the new perimeter be?
Correct Answer: C
Rationale: To find the new perimeter after scaling the rectangle by a factor of 2, we multiply the original dimensions by 2. The original perimeter is 2(5+10) = 30 inches. After scaling, the new width is 5*2 = 10 inches and the new length is 10*2 = 20 inches. The new perimeter is 2(10+20) = 60 inches. Therefore, the correct answer is C. Choice A (30 inches) is incorrect because that is the original perimeter, not the new perimeter after scaling. Choice B (40 inches) is incorrect because it does not consider the correct scaling factor. Choice D (50 inches) is incorrect as it miscalculates the new perimeter after scaling.
Question 4 of 5
If a product's original price is $80 and it is discounted by 20%, what is the final price?
Correct Answer: A
Rationale: To calculate the final price after a 20% discount, you first find the discount amount by multiplying the original price ($80) by the discount percentage (20% = 0.20), which equals $16. Then, subtract the discount amount from the original price to get the final price: $80 - $16 = $64. Therefore, the correct answer is A. Choice B ($60) is incorrect because it does not account for the correct discount amount. Choice C ($70) is incorrect as it does not reflect the correct calculation after applying the discount. Choice D ($66) is incorrect as it does not consider the accurate discount percentage applied to the original price.
Question 5 of 5
In a class of 30 students, with 60% boys and 40% girls, how many girls are in the class?
Correct Answer: B
Rationale: Step 1: Calculate the number of boys in the class. 60% of 30 students = 0.6 * 30 = 18 boys. Step 2: Calculate the number of girls in the class. Since there are 30 students in total, and 18 are boys, there must be 30 - 18 = 12 girls. Therefore, the correct answer is B: 12 girls. Other choices are incorrect because they do not align with the given percentages and total number of students.
