A proportion is an equation that states that two ratios are equal. It can be expressed in the form of a:b = c:d, where a, b, c, and d are numbers representing the quantities in each ratio. For example, if there are 2 apples for every 3 oranges, this can be written as the proportion 2:3 = 4:6, which means that if you double the quantities, you still maintain the same ratio. Proportions are often used to solve problems involving equivalent relationships between two sets of numbers.
