Fraction Buster Method and Proportions

The video tutorial covers solving proportions using the Fraction Buster method, also known as cross multiplication. It begins with an introduction to the method, followed by a detailed explanation of how to apply it to a given proportion. The tutorial then demonstrates the simplification process and concludes with solving for the variable X. The video emphasizes algebraic reasoning and provides a step-by-step guide to ensure understanding.

What is the third method for solving proportions introduced in the video?

• Fraction Buster Method

• Graphical Method

• Substitution Method

What is the equation set up in the video for solving the proportion?

• 4/5 = X/2

• 5/4 = X/2

• 4/5 = 2/X

• 5/4 = 2/X

What is the first step in the Fraction Buster method?

• Divide both sides by the numerators

• Subtract the numerators

• Multiply both sides by the denominators

• Add the denominators

What is the purpose of using the Fraction Buster method?

• To multiply fractions
