Integers are a subset of the set of all rational numbers. By definition, a rational number can be exactly expressed as the ratio of two integers. Only if the ratio can be simplified so that the denominator is 1 is a rational number an integer.
All integers are rational numbers.
Rational numbers and irrational numbers are two completely different groups. A rational number is a number that can be expressed as a fraction of whole integers. An irrational number is a number that cannot be expressed as a fraction of whole integers. So a number is either rational or irrational.
It is a negative rational number.
Integers are aproper subset of 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.
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.
Because integers can be written as fractions. Any number that can be written as a fraction is a rational number.
Yes, all whole numbers (integers) are rational. Please note though that not all rational numbers are integers.
