Answer 1

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.
