Write the smallest and the largest rational number without finding out the LCM. - 1 2 , - 5 1 , 3 2 , 2 7 , 17 12 , 2 1 , - 2 9 and - 12 6 . Give reason for your answer.

Given, rational numbers - 1 2 , - 5 1 , 3 2 , 2 7 , 17 12 , 2 1 , - 2 9 and - 12 6 . We have to find out the smallest and the largest rational number without finding the LCM. Now, let us first separate the negative and positive rational numbers. - 1 2 , - 5 1 , - 2 9 , - 12 6 and 3 2 , 2 7 , 17 12 , 2 1 A rational number on a number line is always greater than the rational number on its left. The rational number - 5 1 lies on the extreme left side and thus is the smallest number, whereas 2 1 lies on the extreme right and thus is the largest number. Hence, the smallest number is - 5 1 and the largest number is 2 1 .
