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.

When can cross multiply be used as a shortcut to the solution while solving rational expressions?
in division
How do you solve problems involve rational algebraic expressions?
To solve problems involving rational algebraic expressions, first, identify any restrictions by determining values that make the denominator zero. Next, simplify the expression by factoring and reducing common factors. If the problem involves equations, cross-multiply to eliminate the fractions, then solve for the variable. Finally, check your solutions against the restrictions to ensure they are valid.
How will you find the value of the unknown in a given rational equation?
Try to cross multiply if possible or set the denominators equal to each other Cross multiplying is when a/b = c/d Which is equal to ad = bc
Do you cross multiply with fractions?
yes
Can any of the steps to soliving rational equations be eliminated?
Yes, some steps in solving rational equations can be simplified or eliminated depending on the specific equation. For instance, if the denominators are the same, you can directly equate the numerators without needing to cross-multiply. However, it's essential to ensure that you still account for any restrictions that the denominators may impose, as this can affect the validity of the solution. Always verify your final solutions by substituting them back into the original equation.

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.
