The answer to 3 feet 9 inches minus 7 feet 11 inches (3' 9" - 7' 11") is displayed below:
- 4 feet 2 inches
Here is how we calculated 3 feet 9 inches minus 7 feet 11 inches to get the answer above:
First, we converted feet to inches so we are only dealing with inches.
3 feet 9 inches = 45 inches
7 feet 11 inches = 95 inches
Then, we deducted 95 inches from 45 inches to get the total number of inches:
45 - 95 = -50 inches.
Finally, we converted -50 inches into feet and inches to get the answer.
3' 9" - 7' 11" = - 4' 2"
Note: There are 12 inches in a foot. Thus, you multiply feet by 12 to get only inches, and
to make it back to feet and inches we divided the total number of inches by 12.
