Class 6 NCERT Ganita Prakash Chapter 7 Fractions
If the unit length between 0 and 1 is divided into two equal parts, the blue line spans one section, making its length 1/2. For the black line, its length is determined by how many segments it covers. For instance, if it spans one part out of two, its length is also 1/2. Alternatively, if it spans multiple parts, the fraction adjusts accordingly. Fractions accurately describe lengths based on proportional representation.
