Repetend
Repetend is a skill on Pengi from Lesson 30: Repeating Decimals in Saxon Math, Course 3.
Key Concepts
Property The repeating digits in a decimal are called the repetend. We indicate repeating digits with a bar over the repetend, such as writing $0.272727...$ as $0.\overline{27}$.
Examples The fraction $\frac{1}{6}$ becomes the decimal $0.1666...$, which is written as $0.1\bar{6}$. The fraction $\frac{3}{11}$ becomes the decimal $0.272727...$, which is written as $0.\overline{27}$. The mixed number $2\frac{1}{3}$ is written as $2.\bar{3}$ since $\frac{1}{3} = 0.\bar{3}$.
Explanation Some fractions are like a broken record, creating decimals with a repeating pattern. Instead of writing forever, just draw a bar over the part that repeats—the repetend! It's the ultimate math shortcut for 'this goes on and on', keeping your work neat, tidy, and delightfully dramatic.
