Finding Equivalent Ratios Made Easy

In this video, Mr. J explains equivalent ratios, similar to equivalent fractions, using multiplication and division. He provides four examples: finding equivalent ratios for given numbers and identifying them from multiple choices. The video emphasizes the importance of maintaining the same operation on both numbers in a ratio and highlights the role of order in determining equivalency.
