To find the number \( x \) that completes the sentence "David's weight \( x \) _____ = his nephew's weight," we can set up the equation:
David's weight (147.6 pounds) divided by his nephew's weight (14.76 pounds):
\[ x = \frac{\text{David's weight}}{\text{nephew's weight}} = \frac{147.6}{14.76} \]
Calculating this:
\[ x \approx 10 \]
So the completed sentence would be:
"David's weight \( 10 \) times = his nephew's weight."
Thus, the answer is \( 10 \).
