(b) what is the length of the fish in inches?
inches

Explanation:

Step1: Define conversion factor

1 foot = 12 inches

Step2: Fill double number line

Top line (feet): Mark 4.5 at the arrow
Bottom line (inches): First calculate the value for the arrow: $4.5 \times 12 = 54$, so mark 54 at the arrow

Step3: Calculate total inches

Multiply feet by conversion factor:
$4.5 \times 12 = 54$

Answer:

(a) Double number line:
Top line (feet): 0, 4.5
Bottom line (inches): 0, 54
(b) 54 inches
