Fraction of a whole numbers are explained here with 4 following examples.
There are three shapes:
(b) rectangle-shape and
Each one is divided into 4 equal parts. One part is shaded, i.e., one-fourth of the shape is shaded and three parts of the shape is unshaded.
We say that, 1/4 of the shape is shaded and 3/4 of the shape is unshaded.
This 1/4 or 3/4 is a fraction or a fractional number.
1/4 = Out of 4 equal parts of a whole, one part is taken.
3/4 = Out of 4 equal parts of a whole, 3 parts are taken.
(ii) The rectangular shape is divided into 5 equal parts. 2 parts of this rectangle are shaded. The total parts of a whole are 5. Each equal part of the whole shape is 1/5. Two equal parts (shaded part) of the whole is 2/5. Three equal parts (unshaded parts) of the whole is 3/5.
2/5 means 2 parts out of 5 equal parts. We read it two-fifths or two by five.
(iii) There is a collection of 7 glasses, of which 4 glasses are colorful.
Thus, 4/7 part of the collection of 7 glasses are coloured.
(iv) There are 12 hearts in a collection. 5 hearts are in shaded parts.
5 out of 12 hearts are in shaded portion and the rest 7 out of 12 hearts are in unshaded portion.
They represent 5/12 and 7/12 as fractions.
