Irrational numbers class 9
WebRational numbers: 2/9 and 3/8 Let us rationalize the numbers, By taking LCM for denominators 9 and 8 which is 72. 2/9 = (2×8)/ (9×8) = 16/72 3/8 = (3×9)/ (8×9) = 27/72 Since, 16/72 < 27/72 So, 2/9 < 3/8 The rational number between 2/9 and 3/8 is Hence, 3/8 > 43/144 > 2/9 The descending order of the numbers is 3/8, 43/144, 2/9 2.
