Question 70 (iv)

Express the following rational number in its standard form:
$\frac{299}{-161}$

Answer 1

Given rational number is $\frac{299}{-161}$

For standard form of given rational number
$=\frac{299÷23}{-161÷23}$ [$\because$ HCF of 299 and 161 = 23]

$=\frac{13}{-7}$

$=\frac{13÷(-1)}{-7÷(-1)}$ [dividing by (-1) in both numerator and denominator]

$=\frac{-13}{7}$

Hence, the standard form of $\frac{299}{-161}$ is $\frac{-13}{7}$
