To find the appropriate number \( x \) that completes the sentence "David's weight \( x = \) his nephew's weight," we can set up the equation using their weights:
David's weight: 147.6 pounds
Nephew's weight: 14.76 pounds
We need to determine which option \( x \) makes the equation valid:
\[ 147.6 \times x = 14.76 \]
To solve for \( x \):
\[ x = \frac{14.76}{147.6} \]
Calculating this:
\[ x = 0.1 \]
Thus, the appropriate number to complete the sentence is:
B) 0.1
