Question

which of the two rational number is greater in each of the following pairs 9/-13 or 7/-12 with picture​

Answer 1

Answer:

7/-13 is greater

Step-by-step explanation:

The LCM of the denominators 13 and 12 is 156

∴13−9=(13×12)(−9×(12))=156−108

and 12−7=(12×13)(−7×(13))=156−91

Now, −108<−91

⇒156−108<156−91

⇒13−9<12−7

⇒−139<−127

∴−127 is greater.
