The answer to 11 feet 10 inches plus 3 feet 11 inches (11' 10" + 3' 11") is displayed below:
15 feet 9 inches
Here is how we calculated 11 feet 10 inches plus 3 feet 11 inches to get the answer above:
First, we converted feet to inches so we are only dealing with inches.
11 feet 10 inches = 142 inches
3 feet 11 inches = 47 inches
Then, we added the inches together to get the total number of inches:
142 + 47 = 189 inches.
Finally, we converted 189 inches into feet and inches to get the answer.
11' 10" + 3' 11" = 15' 9"
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 total number of inches by 12.
