Question

Express the following rational number in the standard form: $\left(ii\right)\frac{5}{-12}$

Answer 1

Converting the rational number into standard form

Given, rational number is $\frac{5}{-12}$.

[A rational number is said to be in standard form if its denominator is positve in the lowest term]

Multiplying $-1$ with both numerator and denominator to make the denominator positve

$\frac{5}{-12}=\frac{5\times (-1)}{-12\times (-1)}=\frac{-5}{12}$

Hence, standard form of given rational number is $\frac{-5}{12}$.
