Answer:
1. cannot be simplified anymore
2. 1/3
3. 1/9
4. cannot be simplified anymore
5. cannot be simplified anymore
6. cannot be simplified anymore
Explanation:
1. It can't be because 9 can only be done with 3 and 32/3 is not a whole number so it cannot be simplified.
2. It is 1/3 because 15 can be simplified down in both of them because 45/15=3.
3. It is 1/9 because 2/2=1 and 18/2=9.
4. It cannot be simplified because 7 is not able to be multiplied besides 1 and 7.
5. It cannot be simplified because 7 is not able to be multiplied besides 1 and 7.
6. It cannot be simplified because 5 can only be multiplied by 1 or 5. 44/5 would not be a whole number so you can't simplify it anymore than that.
