Помогите пожалуйста!!!
7 2/7 - 3 1/7 4 1/7 4 1/7 29/7
---------------- = -------------- = ----------- = ----------- = 29/7 : 56/15 = 29/7 * 15/56 =
12/3 * 56/60 1/3 * 56/5 56/15 56/15
= 435/392 = 1 43/392
(125/144 - 25/144 + 17 11/13) : 1/2 = (100/144 + 232/13) : 1/2 = (1300/1872 + 33408/1872) : 1/2 = 34708/1872 : 1/2 = 34708/1872 * 2 = 34708/936 = 37 76/936 = 37 38/468 = 37 19/234
