Converting Repeating Decimals to Fractions

In this video, Mr. J explains how to convert repeating decimals to fractions, focusing on cases with both non-repeating and repeating digits. The video covers two examples: converting 0.247 repeating and 9.16 repeating into fractions. The process involves writing equations, shifting decimal places, and simplifying fractions. Mr. J emphasizes the importance of understanding each step and provides a method to verify the results. The video concludes with a summary of the conversion process.
