Question

are rational numbers sometimes integers?

Answer 1

Yes, rational numbers can be integers. A rational number is defined as any number that can be expressed as the quotient of two integers, where the denominator is not zero. For example, the integer 5 can be expressed as the fraction \( \frac{5}{1} \), which makes it a rational number. Similarly, negative integers like -3 can also be expressed as \( \frac{-3}{1} \), confirming that they are rational numbers as well. In summary, all integers are rational numbers, but not all rational numbers are integers.
