Conver measuring unit ft to in

Question

9 ft 10 in = ___in I don’t understand how to convert this problem

Answer 1

Since the 10 is already in inches, we can leave this part alone for now.

For the 9 ft, there are 12 inches in 1 foot.

To determine the number of inches:

9 x 12 = 108 inches

Now add in the 10 inches

108 + 10 = 118 inches
