Reduce the following rational number in its lowest form: 91/-364

Solution:

Given, the rational number is 91/-364

We have to reduce 91/-364 to its lowest form

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

91 = 7 × 13

364 = 2 × 2 × 7 × 13

HCF of 91 and 364 = 7 × 13 = 91

Now, 91/91 = 1

-364/91 = -4

Therefore, 91/-364 = 1/-4
