Four pieces of 1/8 make 1/2. If I divide a whole into 8 equal parts, then 4 of those pieces together form half of the whole. So, 1/2 = 4/8.

class 5 Maths-Mela Mathematics Textbook Chapter 2 Fractions question answer
If a shape is divided into 8 equal parts, each part is 1/8. When I take 4 of these parts, they cover exactly half the shape. That is the same as 1/2. So, 1/2 = 4/8. The fraction kit also shows this because four one-eighth pieces perfectly fit one-half piece. That is how 1/2 and 4/8 are equivalent.
