question_answer 5)

The teacher distributes 5 pencils per student. Can you tell how many pencils are needed, given the number of students? (Use s for the number of students).

Answer:

                Let number of students = s Given, number of pencils distributed to each student = 5 When there is one student i.e. s = 1, then number of pencils = 5 \[\times \] 1 i.e. 5 When there are two students i.e. s = 2, then number of pencils = 5 \[\times \] 2 i.e. 10 When there are three students i.e. s = 3, then number of pencils = 5 \[\times \] 3 i.e. 15 When there are s students i.e. s = s, then number of pencils = 5 \[\times \] s i.e. 5s Hence, 5s pencils are needed for s students.
