Converting Fractions to Decimals and Percents

This video tutorial explains how to convert a fraction into a decimal and then into a percent. The example used is the fraction 2/15. The instructor demonstrates the long division method to convert the fraction into a repeating decimal, 0.1333, with the digit 3 repeating. The video then shows how to convert this decimal into a percentage by moving the decimal point two places to the right, resulting in 13.3% with the 3 repeating. The tutorial concludes with a brief mention of additional resources for further learning.
