• To make the fractions easier to multiply

• To correctly add the fractions

What is the result of adding 8/4X and 3/4X?

• 5/4X

• 3/4X

• 11/4X

• 8/4X

What is the first step in solving a proportion using the cross product?

• Cross multiply the terms

• Multiply the denominators

• Divide the terms

• Add the numerators

What is the solution for x in the equation 20x = 11?

• x = 11/20

• x = 11

What is the purpose of multiplying the entire equation by the LCD?

• To add fractions

• To simplify the equation

• To find the solution directly

• To clear out the fractions

What is the LCD of the denominators x, 4x, and 1?

• x

• 1

• 4

• 4x

What is an extraneous solution?

• A solution that is derived from the numerator

• A solution that simplifies the equation

• A solution that is not part of the original equation

• A solution that is always correct

Why is it important to check for extraneous solutions?

• To ensure the equation is balanced
