问：(1/11+3/13+5/17+7/19+2/31)÷(4/11+8/31+12/13+20/17+28/19)

答：亲！你好为你解答！(1/11 + 3/13 + 5/17 + 7/19 + 2/31) ÷ (4/11 + 8/31 + 12/13 + 20/17 + 28/19)= (101005/1222057 + 72849/1222057 + 84885/1222057 + 46221/1222057 + 8110/1222057) ÷ (404020/1222057 + 318520/1222057 + 904176/1222057 + 244740/1222057 + 219452/1222057)= (371070/1222057) ÷ (1907148/1222057)= (371070/1222057) x (1222057/1907148)= 0.1934.

答：亲！**) / (720***) = 84885 / 1222057(7/19) = (7/19) x (643***) / (643***) = 46221 / 1222057(2/31) = (2/31) x (395***) / (395***) = 8110 / 1222057(4/11) = (4/11) x (111***) / (111***) = 404020 / 1222057(8/31) = (8/31) x (395***) / (395***) = 318520 / 1222057(12/13) = (12/13) x (943***) / (943***) = 904176 / 1222057(20/17) = (20/17) x (720***) / (720***) = 244740 / 1222057(28/19) = (28/19) x (643***) / (643***) = 219452 / 1222057
