If the length of a board is 80 inches, how many feet long is it?

To convert inches to feet, it’s essential to know that there are 12 inches in one foot. Therefore, to find the length in feet, you divide the total number of inches by 12.

In this case, if you take the length of the board, which is 80 inches, and divide it by 12, you perform the following calculation:

80 inches ÷ 12 inches/foot = 6.6667 feet

When rounded to two decimal places, 6.6667 feet is approximately 6.67 feet, which is equivalent to 6 and 2/3 feet. However, when expressed more accurately, this can also be represented as 6.75 feet (since 2/3 of a foot is 0.67).

Therefore, the most precise answer among the choices that matches this calculation is 6.75 feet.
