1. In the storeroom, folders are stored in
packages of 8. What is the least number of
packages needed for a class of 35 students?
2. The cafeteria workers store small milk cartons
in the refrigerator in stacks of 6. If each worker
carries no more than one stack, what is the least
number of cafeteria workers needed to carry
small milk cartons for a class of 32?
3. In the teachers’ lunchroom, teachers sit at tables
for 6. There are 22 teachers eating lunch. How
many tables must be set up?
1. 5?
2. 4?
3. 4?
Please tell me if the answers are right or wrong and explain.
1 and 3 are right. 2 is wrong.
is the answer 2?
No.
32/6 = 5 2/6 = 5 1/3
Since we can't have 1/3 of a worker, it will take six workers to carry 32 cartons of milk.
The answers provided are incorrect. Let me explain the correct way to solve each question:
1. In the storeroom, folders are stored in packages of 8. To find the least number of packages needed for a class of 35 students, divide the total number of students by the number of folders in one package:
35 students ÷ 8 folders per package = 4.375
Since we can't have a fraction of a package, we need to round up to the nearest whole number. Therefore, the least number of packages needed is 5.
So, the correct answer is 5.
2. In the cafeteria, small milk cartons are stored in stacks of 6, and each worker can carry no more than one stack. To find the least number of cafeteria workers needed to carry small milk cartons for a class of 32, divide the total number of cartons by the number of cartons in one stack:
32 cartons ÷ 6 cartons per stack = 5.333...
Since we need to have whole numbers of stacks, we need to round up to the nearest whole number. Therefore, the least number of cafeteria workers needed is 6.
So, the correct answer is 6.
3. In the teachers' lunchroom, teachers sit at tables for 6. To find the number of tables that must be set up for 22 teachers, divide the total number of teachers by the number of teachers sitting at one table:
22 teachers ÷ 6 teachers per table = 3.666...
Since we need to have whole numbers of tables, we need to round up to the nearest whole number. Therefore, the number of tables that must be set up is 4.
So, the correct answer is 4.
Therefore, the correct answers to the questions are:
1. 5
2. 6
3. 4
