Question 7
Arrange the following rational numbers in descending order:
-7 -11 2 19
(ii)
10' 15' -5° -30
Solution:​

Answer 1

◆Solution◆

19> 2> -7> -11

Note: In positive numbers the bigger number is taken as the bigger number whereas in negative numbers, the smallest number with the negative sign is taken as the biggest. For eg (-7) and (-11). Here the 7 is smaller number than 11 if it is positive. But it has '-' sign before the number. So in negative numbers the smaller is the biggest and is a universal fact.

(ii) Try it yourself (use what I wrote in the note).
