How Cross Multiplication Works
Cross multiplication is a method used to solve proportions, which are equations where two ratios (fractions) are equal.
The Formula:
If \( \frac{a}{b} = \frac{c}{d} \), then \( a \times d = b \times c \)
Steps to Solve for an Unknown 'x':
- Set up the proportion with the unknown value 'x' in one of the positions (a, b, c, or d).
- Multiply the numerator of the first fraction by the denominator of the second fraction.
- Multiply the denominator of the first fraction by the numerator of the second fraction.
- Set the two products equal to each other.
- Solve the resulting equation for 'x'.
