Yes, they all are. A rational number is one that can be written as a fraction. Any integer can be written as a fraction by putting it on top (making the integer the numerator) and putting a "1" on the bottom.
Yes. Absolutely EVERY integer is a rational number. A rational number is one that can be written as a RATI0 (fraction) of two integers. So for example, 7 is an integer but could also be represnted by 14/2 or 21/3 etc. Even 0 can be 0/7 or 0/91 etc.
Not all rational numbers are integers, but all integers are rational.
They can be and are.
Yes, they can.
Yes.
False, because integers are whole numbers and rational numbers are not whole numbers.
All integers are rational numbers.
Every counting number, and the negative of it, are real, rational integers.
-5 is an integer and a rational number. Integers can be positive or negative. Rational numbers can be expressed as a fraction of integers.
Integers are rational.
Any number that can be expressed as the ratio of two integers is a rational number.
All integers are rational numbers.
Integers are aproper subset of rational numbers.

Not quite. A rational number is a ratio and each rational number is a ratio of specific pairs of integers - not ANY two integers. And, of course, 0 is not allowed on the denominator.
Rational numbers include integers, but they also include fractions.
Yes, all whole numbers (integers) are rational. Please note though that not all rational numbers are integers.
Because integers can be written as fractions. Any number that can be written as a fraction is a rational number.
not necessarily... An integer is a rational number, but so is any real number between consecutive integers.
