Converting Fractions to Percents

Lesson 25 focuses on converting fractions to percents. It begins with creating ratios from diagrams, specifically using cars and trucks as examples. The lesson then explains how to convert these ratios into percents using the TRF method, emphasizing the importance of finding equivalent ratios with a denominator of 100. Alternative methods, such as double line diagrams, are also introduced to provide different approaches to the conversion process. The lesson concludes with modeling these concepts using diagrams to reinforce understanding.

What is the first step in converting fractions to percents as discussed in the lesson?

• Finding the least common multiple

• Subtracting fractions

• Setting up ratios using a diagram

• Adding fractions together

How do you convert a ratio to a percent according to the lesson?

• Add 50 to the ratio

• Find an equivalent ratio with a denominator of 100

• Multiply the ratio by 10
