How can you use ratios and rates to solve a problem?

RatiOS and rates can be used to solve problems by comparing quantities and determining their relationships. For instance, if you need to find out how much of a resource is required for a specific output, you can set up a ratio based on known values. By cross-multiplying or scaling the ratio, you can calculate unknown values efficiently. Additionally, rates can help in situations involving time, speed, or cost, allowing you to make informed decisions based on proportional relationships.
