# What Value Of X Makes This Proportion True

## Understanding Proportions

Proportions are mathematical expressions of equality between two ratios. They are essential in various fields, including mathematics, science, and statistics. In a proportion, the relationship between the quantities remains constant regardless of their scale.

## The Proportion Equation

A proportion can be written as:

a/b = c/d

Where a, b, c, and d are numbers. To solve for x when given a proportion, you need to find the value of x that makes the proportion true.

## Steps to Find x in a Proportion

1. Cross Multiply: Multiply the outer numbers (a and d) and the inner numbers (b and c) of the proportion equation.
2. Set up an Equation: Create an equation from the cross products obtained in the previous step.
3. Solve for x: Solve the equation to find the value of x.

## Example Problem:

Given the proportion: 2/x = 4/6

Let’s solve for x:

1. Cross Multiply: 2 * 6 = 4 * x
2. Set up an Equation: 12 = 4x
3. Solve for x: x = 12 / 4 = 3

Therefore, the value of x that makes the proportion 2/x = 4/6 true is x = 3.
