There is no integer that satisfies both of those conditions.
There is no integer that is greater than 10 and less than negative 15, as these two conditions cannot be satisfied simultaneously. The range of integers greater than 10 starts at 11, while those less than negative 15 start at -16. Therefore, no integer exists that meets both criteria.

By an integer, no. By any proper fraction, yes.
The only two integer numbers greater than 12 and less than 15 are 13 and 14. Of these, only 14 is even. Therefore, the answer is 14.
Any integer greater than one can be co-prime.
5
It is any fraction of the form 7/n where n is an integer which is greater than 7 and is coprime with it.
No, you can't divide 15 by a number greater than 1 and get an answer greater than 15. All mixed numbers are greater than 1 by definition.
The LCM of 15 and 18 is 90.
