Express the following rational number in its standard form: 299/-161

Solution:

Given, the rational number is 299/-161

We have to express the given rational number in its standard form

We know that, to reduce the rational number to its standard form, we divide its numerator and denominator by their HCF

299 = 13 × 23

161 = 23 × 7

HCF of 299 and 161 = 23

Now, 299/23 = 13

-161/23 = -7

So, 299/-161 = 13/-7

Therefore, the standard form of 299/-161 = -13/7
