Answer 2

Given:

A rational number (-21/28).

To Find:

The standard form/ simplest form of the given rational numbers.

Solution:

The given problem can be solved using the concepts of fractions.

1. The given fraction is (-21/28).

2. The standard form of a fraction implies the simplest form of the numerator and the denominator. The H.C.F numerator and denominator of the fraction are always 1.

3. The given fraction (-21/28) can be also written as,

=>$\frac{-21}{28} = -\frac{7 * 3}{7 * 4}$,
