Quantities refer to the amount or number of something. They help us understand how much of an item we have, whether it's a few apples, several books, or a large number of stars in the sky. Quantities can be measured in different ways, such as counting individual items or using units like liters for liquids and kilograms for weight. In everyday life, we often deal with quantities when cooking, shopping, or planning events. For example, a recipe might call for a specific quantity of flour, while a grocery list helps us keep track of how many eggs we need. Understanding quantities makes it easier to manage our resources effectively.
