Answer: The school should buy 7 packages of notebooks.
Explanation: To find the number of packages that the school should buy, we need to divide the total number of notebooks by the number of notebooks in each package. This is because each package contains a fixed number of notebooks, and we want to know how many times that number fits into the total number. This is also called finding the quotient of two numbers.
To divide 105 by 15, we can use long division or a calculator. Using long division, we get:
7
15|105 -105 0
This means that 105 divided by 15 equals 7 with no remainder. Therefore, the school should buy 7 packages of notebooks to get exactly 105 notebooks. If the school buys more packages, it will have extra notebooks. If the school buys less packages, it will not have enough notebooks.
Alternatively, using a calculator, we can enter 105 / 15 and get the same answer of 7.
Hope this helps, and have a great day! =)
