Converting Fractions to Percents

In this video, Mr. J explains how to convert fractions to percents by hand without using a calculator. The process involves dividing the numerator by the denominator to get a decimal, then multiplying the decimal by 100 to convert it to a percent. Two examples are provided: converting 3/4 to 75% and 7/15 to a repeating decimal, which is then rounded to 46.7% or 47%. The video concludes with a summary of the steps and options for handling repeating decimals.
