Learn to solve a proportion in two different ways ex 9, 5/2n = 3

The video tutorial explains how to solve proportions using two methods: multiplication and cross product. The first method involves multiplying both sides to eliminate the variable from the denominator, while the second method uses the cross product technique. Both methods are demonstrated with examples, and students are encouraged to choose the method they prefer.

What is the first step in solving a proportion by removing the variable from the denominator?

• Add the variable to both sides

• Multiply both sides by the variable

• Subtract the variable from both sides

• Divide both sides by the variable

When multiplying by 2N, how should you think of the multiplication to simplify the process?

• As multiplying by 1

What is the result of multiplying 3N by 2N in the context of solving the proportion?

• 7N

• 4N

• 5N

• 6N

Which method involves rewriting numbers to apply a cross product?

• Division method

• Cross product method

• Subtraction method

• Addition method

What is the final result of the proportion when using the cross product method?

• 2/1

• 1/2

• 5/6

• 6/5
