-4
Every number except zero is a factor of every other number. Usually this kind of question is intended as a question about integral factors, those that can be paired with another integer to produce the number as a product. In that sense, 9 is not an integral factor of 11, because the paired number with 9 is 11/9, a number that is not an integer.
9
next prime number would be 11
It is: 9 and 11/16 simplified
Yes, 6/7 is bigger than 9/11.
9 over 11.
10 out of 11
9 over 17 is bigger.
9 is smaller than 11. We'd write this as 9 < 11 or 11 > 9.
55
-4
8/9
No.
5/6 or 9/11 cross multiply 5*11 = 55 6*9 = 54 since 55 > 54, then 5/6 > 9/11
No 11 is not divisible by 9 to give a whole number 11 divided by 9 is 1.2 recurring
7/9 > 11/15
