The answer to 9 feet 9 inches plus 1 foot 11 inches (9' 9" + 1' 11") is displayed below:
11 feet 8 inches
Here is how we calculated 9 feet 9 inches plus 1 foot 11 inches to get the answer above:
First, we converted feet to inches so we are only dealing with inches.
9 feet 9 inches = 117 inches
1 foot 11 inches = 23 inches
Then, we added the inches together to get the total number of inches:
117 + 23 = 140 inches.
Finally, we converted 140 inches into feet and inches to get the answer.
9' 9" + 1' 11" = 11' 8"
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.
