One example of a proportion in mathematical terms is:
$$ \frac{2}{4} = \frac{1}{2}$$
A proportion is a statement that two ratios are equal. In other words, a proportion consists of four numbers or expressions, with two on the left side of the equation and two on the right side, and the ratio of the first pair is equal to the ratio of the second pair. The key aspect of a proportion is that the cross-products are equal, meaning that the product of the first and last numbers is equal to the product of the second and third numbers.
