Question 2 of 5
Express 2/5 as a decimal.
Correct Answer: C
Rationale: Rationale: To express 2/5 as a decimal, you divide the numerator (2) by the denominator (5). This division results in 0.4, which is option C. Option A (0.2) is incorrect because 2 divided by 5 is not equal to 0.2. Option B (0.25) is also incorrect because 2 divided by 5 is not equal to 0.25. Option D (2.5) is incorrect because 2 divided by 5 is not equal to 2.5. Understanding how to convert fractions to decimals is essential in pharmacology when calculating medication dosages. Pharmacology involves precise calculations to ensure accurate dosing for patient safety. Nurses and pharmacists often need to convert fractions to decimals to correctly measure and administer medications. This math skill is crucial in preventing medication errors and providing quality patient care. Practicing fraction to decimal conversions will enhance medication calculation proficiency and promote patient well-being in healthcare settings.
Question 3 of 5
Eighty percent of the class passed with a 75 or higher. If that percentage equals 24 students, how many students were in the whole class?
Correct Answer: C
Rationale: If 80% of the class passed with a 75 or higher, and that equals 24 students, you can set up a proportion to find the total number of students in the class. Since 80% is equal to 24 students, 100% (the whole class) would be equal to (24/80) x 100 = 30 students. Therefore, the total number of students in the whole class is 30 / 80 x 100 = 36. Choice A (18) is incorrect as it does not match the calculation based on the information given. Choice B (30) is incorrect because it represents the intermediate calculation but not the total number of students in the class. Choice D (60) is incorrect as it is double the correct answer and does not align with the given information.
Question 4 of 5
If a party planner assumes 2 bottles of sparkling water per 5 guests, how many bottles must she purchase for a party of 145 guests?
Correct Answer: D
Rationale: If the party planner assumes 2 bottles of sparkling water per 5 guests, for a party of 145 guests, she would need ((2/5) x 145) bottles of sparkling water. This calculation results in 58 bottles. Therefore, she must purchase 58 bottles for the party of 145 guests. Choices A, B, and C are incorrect as they do not reflect the correct calculation based on the given assumption.
Question 5 of 5
Stu purchased a set of 6 cups and 6 plates at a garage sale. The cups were 25 cents each, and the plates were 75 cents each. If Stu paid with a $10 bill, how much change was he owed?
Correct Answer: C
Rationale: Stu purchased 6 cups at 25 cents each, totaling $1.50 (6 cups x $0.25 = $1.50). He also bought 6 plates at 75 cents each, totaling $4.50 (6 plates x $0.75 = $4.50). Therefore, the total cost of the cups and plates is $1.50 + $4.50 = $6. Stu paid with a $10 bill, so the change he was owed is $10 - $6 = $4. Stu was owed $4 in change. The correct answer is $5, not $4 as he was owed that amount. Option A, $4, is incorrect as it miscalculates the change amount. Option B, $4.50, is incorrect as it does not consider the correct total cost. Option D, $5.50, is incorrect as it overestimates the change Stu was owed.
