  4. One-thirdWhich part of the pizza would you like to eat? How many other people can you equally share the rest of the cake with?This pizza is divided into 3 equal parts. One part of 3 equal parts is called one- third. It is written as 1/3.We get thirds when we divide an object into 3 equal parts. One of three equal parts is called one third.

  5. One-fourthHow many parts of the paper shall we have if we fold it just like below?Each shall have 4 equal parts.We get fourths when we divide an object into 4 equal parts. One of four equal parts is called one- fourth. It is written as ¼ . ---

  6. Fraction Models Fraction can be shown as part of a circle. Here is ¼ of a circle. 1 out of four parts is shaded in so we say one-fourth. Or as part of rectangle Here is ¾ of the rectangle 3 out of 4 parts is shaded in, So we say three-fourths
