The video tutorial by The Maths Guy covers how to find and simplify equivalent ratios. It explains the process of using multiplication and division to create equivalent ratios, emphasizing the importance of applying the same operation to both numbers in a ratio. The tutorial also demonstrates how to simplify ratios to their simplest form by identifying common factors. Additionally, it includes examples of identifying equivalent ratios from a list and concludes with practice questions for viewers to solve.

What is the main principle to remember when finding equivalent ratios?

• Add the same number to both parts of the ratio.

• Multiply or divide both parts of the ratio by the same number.

• Subtract the same number from both parts of the ratio.

• Only change one part of the ratio.
