To create a double number line showing the conversion from feet to inches, we can set it up with two parallel lines: one for feet and one for inches. Here's how you can represent it:
Feet: |---|---|---|---|---|---|---|---|---|---|
0 1 2 3 4
Inches:|----|----|----|----|----|----|----|----|----|----|
0 12 24 36 48
In this double number line:
- Each segment on the feet line represents 1 foot.
- Each segment on the inches line represents 12 inches.
To find the length of the fish in inches:
- Since Susan caught a 4-foot long fish, we can see that 4 feet corresponds to 48 inches (since \(4 \times 12 = 48\)).
Thus, the fish is 48 inches long.
