Identifying and Rounding Decimals

In this video, Mr. J explains how to convert fractions to decimals using a calculator. He demonstrates the process with two examples: 9/16 and 30/35. For 9/16, he shows how to divide the numerator by the denominator to get a decimal and discusses rounding options. For 30/35, he explains how to identify repeating decimals and the importance of rounding. The video concludes with a summary of the conversion process and the use of rounding for long or repeating decimals.
