Explain how the venn diagrams in this lesson show that all integers and all whole numbers are rational numbers

The Venn diagram shows that rational numbers include all integers (-3, -2, -1, 0, 1, 2, 3,) and all whole numbers (0, 1, 2, 3, 4, 5). Inside the rational numbers circle is the integer circle, and the whole numbers circle, which concludes that all integers and whole numbers are rational numbers.
