Converting Fractions to Percentages

In lesson 11d, the video tutorial explains how to convert fractions and mixed numbers into percentages. It covers two methods: converting fractions to decimals first, then to percentages, and directly converting fractions to percentages using cross-cancelling. The video also demonstrates using a calculator for these conversions and discusses handling mixed numbers. The lesson concludes with a preview of upcoming topics.
