It explains the concept of ratios as comparisons between two numbers and demonstrates three ways to write them: using a colon, words, and fractions. The video provides several examples, including scenarios involving sunny and rainy days, lemonade sales, tennis matches, and driving routes, to illustrate how to correctly order and simplify ratios. Tips for using a calculator to simplify fractions are also included.
