How to determine equivalent ratios

The video tutorial explains how to determine if two ratios are equivalent by using examples. It starts with an introduction to equivalent ratios, followed by a demonstration using 1/2 and 2/4. The tutorial then guides viewers on how to determine equivalent ratios by finding a common multiplier. Finally, it provides an example of non-equivalent ratios to illustrate the concept further.

What happens if you multiply the numerator and denominator of a ratio by different numbers?
