A "mixed number" is (a whole number) plus (a fraction). Since part of it is a whole number, a mixed number can't be less than ' 1 '. 53/961 is less than ' 1 ', so there's nothing you can do to it that makes it a mixed number. It just doesn't have what it takes.
No. A mixed number is greater than 1 since it has a non-zero whole number (which is at least 1) and a fraction (which is greater than 0); any number divided by a number greater than 1 will be less than the original number. So 15 divided by a mixed number will be less than, not greater than, 15.
-- The fraction is 9/10 . -- You can't possibly make a mixed number out of it. Every mixed number is more than ' 1 ', but 0.9 is less than ' 1 '. It just doesn't have what it takes to be a mixed number.
