Rhonda Hughes exercise https://www.khanacademy.org/math/ncert-math-class-8-winter-bridge/x07a8c25cbfcc9660:week-1/x07a8c25cbfcc9660:untitled-212/v/classifying-numbers-indian-accent 2025-06-03T10:39:13.727334631Z Classifying numbers There are many categories we can use to classify numbers. Some of those categories are rational numbers, irrational numbers, integers, and whole numbers. Rational numbers are represented as a fraction of two integers, while irrational numbers cannot be represented as a fraction of two integers. Integers are positive and negative numbers that don’t involve fractions or decimals. Whole numbers are a subset of integers — they are non-negative integers.

It's not just a guess! This video reveals the elegant geometric trick to precisely locate irrational numbers. We'll start by reviewing rational numbers and then dive into the challenge of plotting irrational numbers, whose decimals go on forever without repeating. Discover how the ancient Pythagoras Theorem provides a simple, visual method for constructing these points with perfect accuracy. Follow along as we build √2 and √3 step-by-step using just a compass and a straightedge!
