Part A:
The relationship described in the problem is that the town library has 3 times as many books as the school library. If we let \( b \) represent the number of books in the school library, the equation that represents this relationship is:
\[ 3 \times b = 2,676 \]
So the correct multiplication equation is:
3 × b = 2,676
Part B:
To find the number of books in the school library, we can rearrange the multiplication equation into a division equation. The relationship can be expressed as:
\[ b = \frac{2,676}{3} \]
Thus, the correct division equation is:
b = 2,676 ÷ 3
