pencils are sold in packages of 5. explain why you need 6 packages in
order to have enough for 27 students
because if you only buy five you wont have enough pencils for the whole class that's why you need 6
5 * 5 = 25 -- not enough for 27 students
thx
You're welcome.
To determine why you need 6 packages of pencils in order to have enough for 27 students, we first need to find out how many pencils are needed per student. Since pencils are sold in packages of 5, it means that each package contains 5 pencils.
To calculate the total number of pencils needed for 27 students, we multiply the number of students by the number of pencils needed per student:
27 students * 1 package per student = 27 packages
This calculation shows that you would need 27 packages of pencils in total to have enough for each student.
However, since pencils are sold in packages of 5, we need to determine the nearest multiple of 5 that is greater than or equal to 27. In this case, the nearest multiple of 5 that is greater than or equal to 27 is 30, which is 6 times 5.
Therefore, you need to purchase 6 packages of pencils to have enough for 27 students. This will provide a total of 30 pencils, with each student receiving 1 package (containing 5 pencils) and leaving 3 extra pencils.
