Cross multiplication is a method of solving proportion equations that involves multiplying the numerator of one fraction by the denominator of the other fraction, and vice versa. This creates a new equation that can be solved for the variable.

Follow these steps to solve a proportion equation by cross multiplication:

- Write the proportion equation in the form a/b = c/d.
- Multiply the numerator of the first fraction by the denominator of the second fraction, and vice versa.
- Set the products equal to each other.
- Solve for the variable.

Example:

Solve the proportion equation 2/3 = 5/x.

- Write the proportion equation in the form a/b = c/d.

2/3 = 5/x - Multiply the numerator of the first fraction by the denominator of the second fraction, and vice versa.

2 × x = 3 × 5

2x = 15 - Set the products equal to each other.

2x = 15 - Solve for the variable.

x = 15 / 2

x = 7.5

Therefore, the solution to the equation is x = 7.5.
