The usual rule here is to avoid radicals in the denominator. To do this, just multiply top and bottom by the root of 11 in this case.
9 x radical 11 divided by 11
15
That fraction can't be simplified.
It is: 63/77 = 9/11 simplified
9/33 = 3/11
yes-its 6 over 9
It simplifies to 9/11
9 radical 3
Yes. 33/27 = 11/9
9/9 simplified is 1
It is: 27/33 = 9/11 simplified
Yes. 9 over 30 can be simplified to 3 over 10
65/9 cannot be simplified.
