Knowing that each employee works only one shift, then, in relation to the total number of employees, those who work the night shift represent: (A) 2/3 (B) 3/5 (C) 2/5 (D) 1/3 (E) 1/5 🚩Solution: Total 15 employees. Morning: 2/5. 15 = 6 employees. Therefore: 15 – 6 = 9 employees remaining. Afternoon: 2/3 of the remaining, that is: 2/3. 9 = 6 employees. Therefore, the remaining number is: 15 – 6 – 6 = 3 Therefore, there are 3 employees left for the night shift. We conclude that, in relation to the total number of employees, those who work at night represent: 3/15 = 1/5 Answer: 1/5 AND EXAM QUESTIONS WITH PERCENTAGES AND FRACTIONS - Prof. Robson Liers - Mathematically
