What is the sum of 6 feet 10 inches and 8 feet 9 inches?

vivado [14]

Lets first convert everything to inches.

6 feet= 12*6 = 72 + 10 = 82 inches
8 feet= 12*8 = 96+9 = 105 inches

Now add!

82+105 = 187

Now convert them back to feet.

187/12 = 15 feet

12*15 = 180

187 - 180 = 7 inches

15 feet. 7 inches.

Final answer: B. 15 ft. 7 in.
