Final answer:
The division of 27 by 9, resulting in 3, tells us that Carol can make 3 stacks of stamps, with 9 stamps in each stack.
Step-by-step explanation:
The problem that can be solved using the calculation 27 ÷ 9 = 3 is: Carol has 27 stamps. She makes stacks with 9 stamps in each stack. How many stacks does she make? The division operation tells us how many times one number is contained within another, which in this context means figuring out how many stacks of 9 stamps can be made from 27 stamps. So, when we divide 27 by 9, we find that Carol can make 3 stacks of stamps.
