Question

arrange the following rational numbers in ascending and descending order -5/12, -11/8, -15/24, -7/-9 12/36​

Answer 1

To arrange in ascending and descending order first we have to make all denominator equal

so, we should take LCM

LCM of 12,8,24,9,36 is 72

(-5×6)/(12×6) = -30/72

(-11×9)/(8×9) = -99/72

(-15×3)/(24×3) =-45/72

(-7×8)/(-9×8) =-56/-72

=56/72

(12×2)/(36×2) = 24/72

now all denominator are equal

therfore ,

Ascending order

-99/72, -45/72, -30/72, 24/72, 56/72

now putting the question's value

-11/8, -15/24, -5/12, -7/-9, 12/36

Descending order

56/72, 24/72, -30/72, -45/72, -99/72

now putting the question's value

12/36, -7/-9, -5/12, -15/24, -11/8

Hope this will help you most
