The answer to 1 foot 7 inches plus 7 feet 9 inches (1' 7" + 7' 9") is displayed below:
9 feet 4 inches
Here is how we calculated 1 foot 7 inches plus 7 feet 9 inches to get the answer above:
First, we converted feet to inches so we are only dealing with inches.
1 foot 7 inches = 19 inches
7 feet 9 inches = 93 inches
Then, we added the inches together to get the total number of inches:
19 + 93 = 112 inches.
Finally, we converted 112 inches into feet and inches to get the answer.
1' 7" + 7' 9" = 9' 4"
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.
