Рациональные числа. Видеоурок 2. Математика 10 класс

Today we're returning to old friends – rational numbers! 🤓 Yes, those same fractions we studied back in elementary school. But don't yawn! 😉 In 10th grade, we'll look at them from a different perspective, delve deeper into their properties, review operations on them, and learn how they fit into the broader picture of number sets. In this video, we'll refresh our memory of a rational number, learn what an infinite decimal fraction is, and explore the algorithm for representing an infinite repeating fraction as a common fraction. 🧩 So, grab your pens, notebooks, and get ready to dive into the world of rational numbers! 🚀 0:00 Rational Numbers 0:49 Infinite Decimal Fraction 1:08 Infinite Recurring Decimal Fraction 1:50 Pure and Mixed Recurring Fractions 2:21 Representing a Rational Number as a Decimal Fraction 3:10 Finite or Infinite Decimal Fraction 4:08 Representing a Rational Number as a Decimal Fraction 4:57 Representing an Infinite Recurring Fraction as a Vulgar Fraction 5:10 Algorithm for Representing an Infinite Recurring Fraction as a Vulgar Fraction    • Математика 10 класс   📝Digital Encyclopedia: https://app.onlineschool-1.ru/vse-kla... ______________ Join us!
