If you need to simplify a rational expression with two or more terms, you need to find the LCD in order to write the expression as a single fraction. If the denominators have not common factors, then the only way is to multiply each numerator with the all denominators of the other terms.
If you have an equation in the proportion form, then cross multiply.
If both sides of the equation have more than two rational terms, then work at both sides until you have a proportion, then cross multiply. But I would prefer to multiply each term at both sides by the LCD in order to eliminate the denominators.

How do you multiply and divide rational expressions?
When multiplying two rational expressions, simply multiply their numerators together, and their denominators together: (a / b) * (c / d) = (a * c) / (b * d) Dividing one fraction by another is the same as multiplying the first fraction by the reciprocal of the second one: (a / b) / (c / d) = (a / b) * (d / c) = (a * d) / (b * c) This is often referred to as cross multiplication.

How can you stop weird face expressions?
Are you talking to yourself when you do these expressions. If so clear your mind of negative thoughts and cross your arms. Stop walking around so much, stop listening to music and train yourself to keep a straight face always
What does Cross multiplication mean?
Cross multiplication is when you multiply the denominator of a fraction by the numerator of another fraction. Before you cross multiply you want to see if you can simply the fractions.
