Question

Express the following rational number in the standard form: $\left(i\right)\frac{-7}{-8}$

Answer 1

Converting the rational number into standard form

Given, rational number is $\frac{-7}{-8}$.

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

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

$\frac{-7}{-8}=\frac{-7\times (-1)}{-8\times (-1)}$

$=\frac{7}{8}$

Hence, standrd form of given rational number is $\frac{7}{8}$.
