Describe the relationship between rational numbers and whole numbers. Are all rational numbers also whole numbers? Are all whole numbers also rational numbers? Give examples to support your answer. Write in 1-2 sentences

Answer 1

Rational numbers include all numbers that can be expressed as a fraction of two integers, where the denominator is not zero, while whole numbers are a subset of rational numbers that include only non-negative integers (0, 1, 2, ...). Not all rational numbers are whole numbers (e.g., \( \frac{3}{4} \) is a rational number but not a whole number), but all whole numbers are rational numbers because they can be expressed as fractions with a denominator of 1 (e.g., 5 can be written as \( \frac{5}{1} \)).
