Solution

Given rational number is `299/(-161)`

For standard form of given rational number

= `(299 ÷ 23)/(-161 ÷ 23)` ......[∵ HCF of 299 and 61 = 23]

= `13/(-7) = (13 ÷ (-1))/(13 ÷ (-1))`  .....[Dividing by (–1) on both numerator and denominator]

= `(-13)/7`

Hence, the standard form of `299/(-161)` is `(-13)/7`.
