Whole numbers up to and including one billion can be represented and compared in various ways. One common way is the standard form, where the numbers are written using digits. For example, the number 500,000,000 can be written as 500,000,000.

Another way to represent these numbers is through expanded form using powers of ten. In this form, each digit is multiplied by the corresponding power of ten and then added together. For example, the number 500,000,000 can be written as (5 × 10^8) + (0 × 10^7) + (0 × 10^6) + (0 × 10^5) + (0 × 10^4) + (0 × 10^3) + (0 × 10^2) + (0 × 10^1) + (0 × 10^0).

Whole numbers up to one billion are used in various aspects of everyday life. Here are a few examples:

1. Money: Whole numbers are used to represent currency values, such as the price of goods or services. For instance, when buying a car, the price might be $30,000, which is a whole number.

2. Population: Whole numbers are used to represent the population of cities, countries, or even the world. For example, the population of a city might be 500,000 people.

3. Distance: Whole numbers are used to measure distances, such as the length of a road or the height of a building. For instance, the height of the Burj Khalifa in Dubai is approximately 828 meters.

4. Time: Whole numbers are used to represent time, such as the number of hours, minutes, or seconds. For example, a movie might have a duration of 2 hours and 30 minutes.

5. Quantities: Whole numbers are used to represent quantities of items, such as the number of books in a library or the amount of food in a recipe. For instance, a recipe might require 3 cups of flour.

These are just a few examples of how whole numbers up to and including one billion are used in everyday life. They play a crucial role in various fields, including finance, statistics, engineering, and many others.
