17. what's the sum of 6 feet 10 inches and 8 feet 9 inches? a. 14 ft. 7 in. b. 13 ft. 19 in. c. 15 ft. 7 in. d. 15 ft. 19 in.

Choice C

Step-by-step explanation: The correct sum of 6 feet 10 inches and 8 feet 9 inches is 15ft 7 inches.

In order to calculate this, you will first add the inches.

10 inches plus 9 inches equals 19 inches, which is 1 ft 7 inches.

Next, add the feet - 6 ft plus 8 ft equals 14 ft.

To finish, 14 ft plus 1 ft 7 inches equals 15 ft 7 inches, which is choice c.

First: There are 12 inches in a foot.

Second: You can do it 2 ways.

One way you can do it is by converting them to inches and them turning them back to feet. (This is the longer way)

The second way is to add 6 feet and 8 feet and then add 9 and 10 and making sure there are no leftovers after turning it to geet and leftover inches.

I'm going to do way 2. 6 feet and 8 feet is 14 feet. 9 inches and 10 inches is 19 inches. 19 would be converted to 1 foot and 7 inches. Then we add 14 feet and 1 foot and 7 inches together. When we fo that we get 15 feet and 7 inches.

Your answer is 15 feet 7 inches. Hope this helps :)
