Understanding Direct Proportion

Direct proportion describes a relationship between two quantities where they increase or decrease together at a constant ratio. If one quantity doubles, the other doubles as well.

Formula: If two quantities a and b are directly proportional, and c and x are another pair in the same proportion, it can be represented as:

a / b = c / x

Example: If 2 apples cost $1, then to find the cost of 6 apples (assuming direct proportion), we can set up the proportion: 2 apples / $1 = 6 apples / x. Solving for x gives x = $3.

This calculator helps you solve for x when you know a, b, and c.
