Three tables are placed side by side. One table is 4 feet 10 inches wide, another is 6 feet 11 inches wide, and the third is 3 feet 6 inches wide. How wide are they combined?

Write your answer in feet and inches. Use a number less than 12 for inches.

Step 1 ：Given the widths of three tables in feet and inches. One table is 4 feet 10 inches wide, another is 6 feet 11 inches wide, and the third is 3 feet 6 inches wide.

Step 2 ：To find the total width, we need to add the widths of the three tables together. However, since the widths are given in feet and inches, we need to handle these two units separately.

Step 3 ：First, add the feet together: \(4 + 6 + 3 = 13\) feet.

Step 4 ：Next, add the inches together: \(10 + 11 + 6 = 27\) inches.

Step 5 ：Since 1 foot is equal to 12 inches, we can convert 27 inches to feet and inches. \(27 \div 12 = 2\) feet with a remainder of \(3\) inches.

Step 6 ：Add the converted feet to the total feet: \(13 + 2 = 15\) feet.

Step 7 ：So, the combined width of the three tables is 15 feet 3 inches.

Step 8 ：Final Answer: The combined width of the three tables is \(\boxed{15}\) feet \(\boxed{3}\) inches.
