Answer» Step-by-step explanation: Q1. (a) 2/3, 4/9, 5/6 Taking LCM of denominator, we have, = 12/18, 8/18, 15/18 Clealry, 15/18 > 12/18 > 8/18 Therefore, we GET, => Descending order : 5/6 > 2/3 > 4/9 (B) 7/12, 11/36, 37/72 Taking LCM of denominator. = 42/72, 22/72, 37/72 Clearly, 42/72 > 37/72 > 22/72 Therefore, we get, Descending order: 7/12 > 37/72 > 11/36 Q2. Wall PAINTED by Devansh = 2/3 Remaining wall to be painted = 1/3 Wall painted by sister = 1/4(1/3) = 1/12 TOTAL wall painted = 2/3 + 1/12 = (8+1)/12 = 9/12 = 3/4 Hence, 3/4 of the wall is total painted. Q3. (a) 0.8 = 8/10 = 4/5 (b) 2.25 = 225/100 = 9/4 (c) 3.025 = 3025/1000 = 25/8 |
