A proportion is an equation that states that two ratios are equal. It can be represented in the form of a/b = c/d, where a, b, c, and d are numbers, and b and d are not zero. This means that the relationship between the first pair of numbers (a and b) is the same as the relationship between the second pair (c and d).

**Example of a Proportion:**

Consider the ratios 2/3 and 4/6. We can write this as:

2/3 = 4/6

To check if this is a proportion, we can cross-multiply:

2 * 6 = 3 * 4
12 = 12

Since both sides of the equation are equal, we confirm that 2/3 is equal to 4/6, meaning they form a proportion.
