Section 1
The Meaning of Percent
Property
A percent is a ratio that compares a number to 100.
The symbol % means "per hundred," so any percent can be written as a fraction with a denominator of 100.
In this Grade 6 lesson from Big Ideas Math, Course 1 (Chapter 5: Ratios and Rates), students learn how percents relate to ratios and fractions by writing percents as fractions with a denominator of 100 and converting fractions to percents using equivalent fractions. The lesson covers key skills such as simplifying percent-based fractions, converting values like 35% to 7/20, and applying percent reasoning to real-world problems, aligned to standard 6.RP.3c.
