Question

which is greater 9/-13 or7/-12 full explanation​

Answer 1

Answer:

First we write each of the given numbers with a positive denominator. One number = (9/-13) = [(9× (-1))/ (-13×-1)] = (-9/13) One number = (7/-12) = [(7× (-1))/ (-12×-1)] = (-7/12) The LCM of the denominators 13 and 12 is 156 ∴ (-9/13) = [(-9×12)/ (13×12)] = (-108/156) and (-7/12) = [(-7×13)/ (12×13)] = (-91/156) Now, -108 < -91 ⇒ (-108/156) < (-91/156) ⇒ (-9/13) < (-7/12) Hence, (9/-13) < (7/-12) ∴ (7/-12) is greater.Read more on Sarthaks.com - https://www.sarthaks.com/745587/which-of-the-two-rational-number-9-13-or-7-12-grater-in-the-pairs
