Answer 2

Concept:

An expression for a portion of a whole is a fraction.

In general, the whole can be any particular thing or value, and the fraction might be a portion of any quantity out of it.

The top and bottom numbers of a fraction are explained by the fundamentals of fractions. The bottom number reflects the entire number of components, while the top number represents the number of chosen or coloured portions of the whole.

If a number must be divided into four parts, then x/4 is used to indicate the result. In this case, the fraction x/4 represents 1/4 of the number x. Thus, the fraction in this case is 1/4. It denotes a proportion of one in four. It can be read as 1/4 or one-fourth. This is known as fraction.
