Fractions, Decimals, and Percentages

This video tutorial covers the sixth-grade concept of equivalent fractions, decimals, and percents, focusing on Texas standard 6.4g. It uses a problem from the 2021 released STAAR test to demonstrate how to convert a fraction to a decimal and then to a percent. The tutorial explains the process of dividing the numerator by the denominator to get a decimal and then converting that decimal to a percent. It also discusses simplifying fractions by finding the greatest common factor and provides alternative methods for conversion.
