How to solve a proportion equation by cross multiplication?

There are four sets of simplifying algebraic expression worksheets.

• Proportion Equations (monomial)
• Proportion Equations (binomial)
• Proportion Equations (1 monomial & 1 binomial)
• Proportion Equations (2 binomials)

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:

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

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

1. Write the proportion equation in the form a/b = c/d.
   2/3 = 5/x
   
2. Multiply the numerator of the first fraction by the denominator of the second fraction, and vice versa.
   2 × x = 3 × 5
   2x = 15
   
3. Set the products equal to each other.
   2x = 15
   
4. Solve for the variable.
   x = 15 / 2
   x = 7.5

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