To find the value that correctly fills in the blank, we need to equate the left-hand side with the right-hand side of the expression given in the question.
First, we calculate the left-hand side:
\[ 18 + 45 = 63 \]
Next, we simplify the expression on the right-hand side:
\[ 2 + 5 = 7 \]
Now, we have:
\[ 63 = \text{blank} \times 7 \]
To find the value of "blank," we can rearrange the equation:
\[ \text{blank} = \frac{63}{7} \]
Now, calculating the right-hand side:
\[ \frac{63}{7} = 9 \]
Thus, the value that correctly fills in the blank is:
\[ \boxed{9} \]
