The answer to 3 feet 6 inches plus 9 feet 3 inches (3' 6" + 9' 3") is displayed below:
12 feet 9 inches
Here is how we calculated 3 feet 6 inches plus 9 feet 3 inches to get the answer above:
First, we converted feet to inches so we are only dealing with inches.
3 feet 6 inches = 42 inches
9 feet 3 inches = 111 inches
Then, we added the inches together to get the total number of inches:
42 + 111 = 153 inches.
Finally, we converted 153 inches into feet and inches to get the answer.
3' 6" + 9' 3" = 12' 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.
