The only mathematical difference is that the set of integers (excluding 0), with two exceptions, does not have inverses whereas the set of rational numbers (excluding 0) does. This is equivalent to the statement that the set of non-zero integers is not closed under division whereas the set of non-zero rationals is.

What is the relationship between integers and rational numbers?
The set of integers is a proper subset of the set of rational numbers.
What is Difference between a rational number and irrational number?
A rational number can be expressed as a ratio in the form, p/q, where p and q are integers and q > 0.
Is it possible to count the number of rational numbers there are between any two integers?
No. There are infinitely many rational numbers between any two integers.
What is the difference between a rational number that is not an integer and a rational number that is an integer?
When expressed as a ratio of two integers (not intergers!), the simplest form for the integer but not others, has 1 as the denominator.
What is the difference between an irrational number and a rational numbers?
A rational number can be expressed as a ratio of two integers, p/q where q > 0. An irrational number cannot be expressed in such a way.
Difference between rational numbers and rational expressions?
A Rational number is a fraction of two integers; a rational expression is a fraction that contains at least one variable
What is the relationship between integers and rational numbers?

What is the difference between an irrational number and a rational numbers?
A rational number can be expressed as a ratio of two integers, p/q where q > 0. An irrational number cannot be expressed in such a way.
Is a rational number a subset of the set of integers?
not necessarily... An integer is a rational number, but so is any real number between consecutive integers.
What is the difference between ratio and rational numbers?
Rational numbers are equivalent to ratios of two integers (the denominator being non-zero). A ratio is a relationship between two set of values. For example, the ratio of the circumference of a circle to its diameter is pi, which is not a rational number.
Is there any difference between rational numbers and fractions?
no they are one and the same thing. A rational number is defined as any real number that can be expressed as a fraction p/q for two integers p, q.
What is the relationship between a ratio and rational numbers?
A rational number is one which can be expressed as a ratio of two integers.
Is negative 41 rational?
All integers and ratios between two integers are rational numbers. They are defined as p/q where p and q are integers and q is not 0. Therefore -41 is a rational number (and a negative integer as well).
Is the fraction 22 over 7 irrational?
No, it is rational. A rational number is one which can be expressed as a ratio between two integers. Since 22 and 7 are both integers, then 22 over 7 is rational.
