Answer:
21.25 feet or 255 inches.
Explanation:
The first step in this problem is to covert each measurement to the same system of measurement (feet, inches, meters, etc.).
Let's convert 4 inches to feet.
As there are 12 inches in a foot, and 4/12 = 1/3, 4 inches = 1/3 foot.
Now, multiply 1/3 foot by 63 3/4 (the amount of feet in mixed number form).
63 3/4 * 1/3 = 21 1/4, or 21.25.
Therefore, the final answer is 21.25 feet.
If you want the answer in inches, all you have to do is multiply 21.25 by 12, as there are 12 inches in a foot.
21.25*12 = 255.
So, the alternative answer is 255 inches.
