Answer 2

Answer: The required number of notebooks that will fit in the remaining space is 25.

Step-by-step explanation: Given that Kaitlin's bookshelf has 10 inches of space remaining. Each of her notebooks is
`(2)/(5)` inches wide.

We are to find the number of notebooks that will fit in the remaining space.

We will be using the UNITARY method to solve the given problem.

We have

Number of textbooks that will fit in
`(2)/(5)` inches = 1.

So, the number of textbooks that will fit in 1 inch space will be

`(1)/((2)/(5))=(5)/(2).`

Therefore, the number of textbooks that will fit in 10 inches of space is given by

`(5)/(2)*10=25.`

Thus, the required number of notebooks that will fit in the remaining space is 25.
