Answer:
3ft 9 in
Step-by-step explanation:
So, in each foot there's 12 inches. Knowing that, the operation you use is subtraction. So you do 10 ft 1 in - 6 ft 4 in. If you do that operation knowing that 12 inches=1 foot, then you should get 3 ft 9 in.
Please let me know if there is still any confusion.
