Praxis 5003 Practice Test Practice Question
Ben took a 50-question test and answered 70 percent of the questions correctly. Which of the following expressions can be used to find the number of questions Ben answered correctly?
Correct Answer: A
Rationale: To determine how many questions Ben answered correctly, we need to calculate 70 percent of the total 50 questions. Option A, \((70/100) * 50\), correctly represents this calculation, yielding 35 correct answers.
Option B, \(70/100\), only gives the decimal equivalent of 70 percent (0.7) without applying it to the total number of questions.
Option C, \((50/70) * 100\), incorrectly calculates the percentage of questions answered correctly based on the number of correct answers rather than finding the number of correct answers from the total.
Option D, \(50/70\), similarly provides a ratio without determining how many questions were answered correctly.
