Identifying decimal expansion of rational and irrational numbers. Google Classroom. Problem. and the square root of 9 is 3; √9 = 3. Therefore, the number of irrational numbers between 2 and 3 are √ 5, √ 6, √ 7, and √ 8, as these are not perfect squares and cannot be simplified further. Similarly, you can also find irrational numbers, between any other two perfect square numbers. See more Anirrational numberis a real number that cannot be expressed as a ratio of integers; for example, √2 is an irrational number.

Classify the following numbers as rational or irrational: 9 \(-\) \(\sqrt{5}\) a) None of these . b) Irrational . c) Can not determine . d) Rationa . 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. philly boy jay sweet potato pie
