Understanding Ratios

In this video tutorial, Daniel Carrión introduces the concept of ratios, explaining that a ratio is a comparison between two quantities, often expressed as a fraction. He provides examples using blue and red balls, children in a team, and sweets in a package to illustrate how ratios work and how they can be simplified. The video concludes with a call to action for viewers to solve exercises and engage with the content by liking, commenting, and subscribing.
