Proporcionit drejtpërdrejt, often translated as direct proportion, describes a mathematical relationship between two quantities where they change at the same rate. If one quantity increases, the other quantity increases proportionally, and if one quantity decreases, the other quantity decreases proportionally. This means that the ratio between the two quantities remains constant.

Mathematically, if quantity A is directly proportional to quantity B, it can be expressed as A ∝ B. This can be rewritten as an equation using a constant of proportionality, k: A = kB. The constant k represents the factor by which one quantity changes relative to the other.

For example, if the cost of apples is directly proportional to their weight, then buying more apples will cost more, and buying fewer apples will cost less, with the price per kilogram remaining the same. If 2 kilograms of apples cost 4 euros, then 4 kilograms would cost 8 euros, and 1 kilogram would cost 2 euros. Here, the constant of proportionality (k) is 2 euros per kilogram.

Direct proportion is a fundamental concept in mathematics and is widely used in various fields, including physics, chemistry, economics, and everyday problem-solving, to understand and predict how quantities relate to each other. Recognizing and applying direct proportion allows for accurate calculations and comparisons between different scenarios.
