Yes to all three.
Yes
No because 19 is a whole number which means that it is a rational number
It is a whole number so it is rational.
Yes, since it can be written as a ratio of two integers: 19/5
19 is an integer and not a fraction nor a mixed number. However, it can be expressed in rational form as 19/1 which cannot be simplified.

If you mean the fraction 19/7, do an integer division of 19 divided by 7. The integer (whole) part is the whole number in the resulting fraction. The remainder is written on top of the seven, for the fractional part.
-- Any number that you can completely write down using digits, and a decimal point or fraction bar if needed, is rational. -- A rational number is defined as one that can be written as a fraction using whole numbers. -19 can be written as the fraction -19/1 .
It is a rational number because it can be expressed as a fraction in the form of -19/1
No - the positive integer factors of 57 are 1, 3, 19, 57.
