Answer:
Taking LCM for 9 and 13 we get, 9 × 13 = 117 Now we convert the given fractions into its equivalent fractions, then it becomes (7 × 13)/ (9 × 13) and (8 × 9)/ (13 × 9) Therefore (91/117) > (72/117) Hence (7/9) > (8/13) (ii) Given (11/9) and (5/9) As the denominator is equal, they forms equivalent fractions. But we know that 11 > 5 Hence (11/9) > (5/9)Read more on Sarthaks.com - https://www.sarthaks.com/679752/compare-the-following-fractions-by-using-the-symbol-or-or-i-7-9-and-8-13-ii-11-9-and-5-9?show=679754#a679754Taking LCM for 41 and 30 we get, 30 × 41 = 1230 Now we convert the given fractions into its equivalent fractions, then it becomes (37 × 30)/ (41 × 30) and (19 × 41)/ (30 × 31) Therefore (1110/1230) > (779/1230) Hence (37/41) > (19/30)Read more on Sarthaks.com - https://www.sarthaks.com/679752/compare-the-following-fractions-by-using-the-symbol-or-or-i-7-9-and-8-13-ii-11-9-and-5-9?show=679754#a679754Taking LCM for 15 and 105 we get, 5 × 3 × 7 = 105 Now we convert the given fractions into its equivalent fractions, then it becomes (17 × 7)/ (15 × 7) and (119/105) Therefore (119/105) = (119/105) Hence (17/15) = (119/105)Read more on Sarthaks.com - https://www.sarthaks.com/679752/compare-the-following-fractions-by-using-the-symbol-or-or-i-7-9-and-8-13-ii-11-9-and-5-9?show=679754#a679754
