The answer to 7 feet 9 inches plus 10 feet 9 inches (7' 9" + 10' 9") is displayed below:
18 feet 6 inches
Here is how we calculated 7 feet 9 inches plus 10 feet 9 inches to get the answer above:
First, we converted feet to inches so we are only dealing with inches.
7 feet 9 inches = 93 inches
10 feet 9 inches = 129 inches
Then, we added the inches together to get the total number of inches:
93 + 129 = 222 inches.
Finally, we converted 222 inches into feet and inches to get the answer.
7' 9" + 10' 9" = 18' 6"
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.
