Answer 2

Rational Numbers -: When a number can be expressed in $\frac{p}{q}$ form where p and q are integers and q≠0.

So $\frac{-36}{-63} = \frac{36}{63}$

$\frac{36}{63} = \frac{4}{7}$

∴ $\frac{4}{7}$ is in $\frac{p}{q}$ form where p and q are integers and q≠0 so we can consider it as a rational number.

Additional Information -

To identify if a number is rational or not, we can do the following -

• We can see if it is represented in $\frac{p}{q}$ form where q≠0.
• The ratio of the rational number can be represented in decimal form.

Standard form of rational numbers-:

We can say that a rational number is in its standard form when there is no common factor.

For Example ⇒  $\frac{11}{22}$ is a rational number. But it can be simplified to $\frac{1}{2}$ as it's standard form.

Difference between positive and negative rational numbers-:

Positive Rational Number -

• Both numerator and denominator have the same sign.
• All of them are greater than 0.

Negative Rational Number -

• The numerator and denominator have different sign.
• All of them are below 0.
