3 and 3
It is still an integer, which could be negative or positive.
An integer is a whole number. So zero could be the smallest integer.
25 over 5 equals 5 which is an integer. It is not sensible to change an integer or whole number into a mixed number but if you must, you could write it as 50/5
It is a non-integer. It can be a rational fraction (in decimal or rational form); it can be an irrational number (including transcendental numbers); it could be a complex number or a quaternion.
Yes. An integer is a whole number and it can be a positive or negative number, or 0.

It can't be done!
No because it could be a fraction or a decimal
You could write it as a mixed number (12 and 4/4) but it wouldn't be in simplest form. The simplest form of any integer is the integer itself.
See if it is an even number. If it is, it's divisible by 2.
8 is the integer before 9, but a number is not necessarely an integer. You could say 8.9999999... comes before nine, or you could go further and say that any number that is less than nine is before nine, like -2.
