Welcome to today’s fourth lesson, where we initially discussed converting between fractions and decimals. The lesson progressed to exploring the relationship between fractions, percents, and percentages, demonstrating how 0.90 is equal to 90% or 9 out of 10, which can also be represented as the decimal 0.9. We also covered conversion techniques when the denominator doesn’t easily divide into 100, such as multiplying by strategically chosen numbers to achieve a denominator of 100.
