Learn how to solve a rational expression by multiplying by the LCD

The video tutorial covers the process of adding and subtracting fractions by identifying the least common denominator (LCD) and applying it to simplify expressions. It demonstrates the use of the distributive property and solving equations to find the value of X. The tutorial emphasizes the importance of understanding common denominators and simplifying expressions by canceling terms.

What is the first step in adding or subtracting fractions?

• Subtract the numerators

• Multiply the numerators

• Add the denominators

• Find the least common denominator

When simplifying fractions, what should you do if the same term appears in both the numerator and the denominator?

• Divide them by two

• Multiply them

• Add them together

• Cancel them out

What property is used to simplify the expression after multiplying by the LCD?

• Associative Property

• Identity Property

• Commutative Property

• Distributive Property

In solving for X, what is the first step after applying the distributive property?

• Add all constants to one side

• Subtract the smaller X term from both sides

• Divide both sides by the coefficient of X

• Multiply both sides by the same number

What is the final value of X in the given problem?

• 3/4

• 2/3

• 1/2

• 5/6
