Answer: 1 4/7
Explanation:
When converting from an improper fraction to a mixed number, find the largest multiple of the bottom number you can have without going over the top number, and then put that as a whole number. Then, subtract that multiple from the top number, and put the difference as the new top number.
Since 7 goes into 11 one time, and has a remainder of 4, the mixed number is 1 and 4/7.
