Cross multiplication method with detailed steps

### Cross Multiplication Method

Cross multiplication is a technique used to solve equations involving two ratios or fractions. It is especially useful in solving proportion problems of the form \( \frac{a}{b} = \frac{c}{d} \).

Here’s how the cross multiplication method works:

#### Step 1: Set up the proportion
You are given a proportion, which is two ratios set equal to each other:

\[
\frac{a}{b} = \frac{c}{d}
\]

For example, let’s say we have:

\[
\frac{2}{3} = \frac{4}{x}
\]

#### Step 2: Cross multiply
To solve this equation, you cross multiply. This means multiplying the numerator of one fraction by the denominator of
