Answer 2

To solve this problem, let's break it down step by step:

1. Observe the problem: We are given that there are two packs of notebooks, and the total number of notebooks in both packs is 48. One pack has three times as many notebooks as the other pack. We need to find the number of notebooks in the smaller pack.

2. Assign variables: Let's use the variable "x" to represent the number of notebooks in the smaller pack.

3. Set up the equation: We know that the total number of notebooks in both packs is 48. The number of notebooks in the smaller pack is represented by "x," and the number of notebooks in the larger pack is three times that, which is "3x." So, we can set up the equation:

x + 3x = 48

4. Solve the equation: Combine like terms on the left side of the equation:

4x = 48

Divide both sides of the equation by 4 to isolate "x":

x = 48 / 4

Simplify:

x = 12

Therefore, there are 12 notebooks in the smaller pack.

5. Write the answer: The number of notebooks in the smaller pack is 12.
