Answer :
Final answer:
The length of the piece of fishing line that Eric cut off is found by converting the remaining length to the same units as the initial length and subtracting this from the initial length. The equation to represent the problem is 15.3 - 3.2 = 12.1, which equals 12.1 feet.
Explanation:
The problem here involves understanding the conversion between feet and inches, as these are different units of length. Given that 1 foot equals 12 inches, we need to convert everything to the same unit to make the subtraction possible.
So first, let's convert Eric's remaining fishing line length from inches to feet. As mentioned, one foot is equivalent to 12 inches, thus, 38.4 inches divided by 12 gives us 3.2 feet.
Now we subtract this from the original length. Eric started with 15.3 feet of fishing line. If we subtract the 3.2 feet of line he has left, we can find the length of the piece he cut off. So, 15.3 feet minus 3.2 feet equals 12.1 feet.
Thus, the length of the fishing line that was cut off is 12.1 feet. The equation to represent this problem is 15.3 - 3.2 = 12.1.
