Solving Proportions with Cross Multiplication Techniques

The video tutorial covers solving proportions using cross multiplication. It begins with an introduction to cross multiplication, explaining how to multiply opposite numerators and denominators. The tutorial then moves on to solving one-step equations by dividing both sides to find the variable's value. It also addresses solving problems involving decimals and discusses the impact of adding coefficients in front of variables. Finally, the video outlines a step-by-step process for solving proportions, emphasizing the importance of cross multiplication.

What is the first step in solving proportions using cross multiplication?

• Subtract the variable from both sides

• Add coefficients to both sides

• Multiply opposite numerators and denominators

• Divide both sides by the coefficient

In solving proportions, what is the purpose of cross multiplication?

• To eliminate the denominators

• To simplify the equation

• To balance the equation

• To isolate the variable

After cross multiplying, what type of equation do you typically get?

• A differential equation

• A one-step equation

• A quadratic equation

• A two-step equation

What should you do after setting up a one-step equation in cross multiplication problems?

• None of the above

• Add the variable to both sides

• Divide both sides by the coefficient

• Multiply both sides by the variable

How does adding a coefficient in front of the variable affect the steps in solving proportions?

• It requires an additional multiplication step

• No effect, the steps remain the same

• It adds an additional step of subtraction

• It eliminates the need for division

What is the final step in solving proportions when a coefficient is present?

• Divide both sides by the coefficient

• Subtract the coefficient from both sides

• Multiply both sides by the variable

• Cross multiply the terms
