Understanding Ratios and Percentages

The video tutorial explains how percentages can be expressed as ratios or fractions, with a focus on converting percentages to ratios using the concept of 'per 100'. It demonstrates the simplification of ratios by identifying the greatest common factor between the numerator and denominator. The tutorial provides examples, such as 88% of college students having smartphones and 75% of community college students working part-time, to illustrate the process of simplifying ratios and fractions.
