To find the blank that makes the equation true, you can set up the equation as:
\[ \frac{63}{x} = 9 \]
To solve for \( x \), multiply both sides by \( x \):
\[ 63 = 9x \]
Now, divide both sides by 9:
\[ x = \frac{63}{9} \]
Now calculate \( \frac{63}{9} \):
\[ x = 7 \]
So, 63 divided by 7 equals 9. The blank is 7.
