Definition
A proportion is an equation that states that two ratios are equal.
Description
Understanding proportions is essential in mathematics, as it is used to solve problems involving ratios and fractions. Proportions are commonly seen in real-world applications such as cooking, map measurements, and scale models.
To illustrate, if there are 2 apples for every 3 oranges, the proportion can be expressed as 2:3. Solving proportions involves finding and solving an equivalent ratio.
Teacher's Script: "If you know a recipe requires 2 cups of sugar to 5 cups of flour, that can be written as a ratio of 2:5. You can use this ratio to find how much of each ingredient is needed for larger batches of this recipe."
