To express \( \frac{45}{7} \) in the format \( \frac{?}{?} \), we can simply rewrite it as:
\[ \frac{45}{7} \]
This means that the answer is:
\[ [45] [7] \]
If you are looking for a different representation, \( 45 \div 7 = 6.42857 \), which can also be represented as:
\[ 6 + \frac{3}{7} \]
In the fraction form, it is:
\[ \frac{45}{7} = \frac{6 \cdot 7 + 3}{7} = \frac{42 + 3}{7} = \frac{45}{7} \]
So you could also express it as:
\[ [45] [7] \quad \text{or, in mixed form, } [6] [3] [7] \]
