Решите пример с дробями. )это дробная черта 28)33*45)98:2 3)11=
28/33×45/98=1260÷3234=630/1617= 210/539 210/539÷25/11= 210/539×11/25= 2310/13475= 462/2695=66/385
28/33 * 45/98 : 2 3/11 = 6/35 1) 28/33 * 45/98 = 28 * 45/33 * 98 = 1260/3234 = 30/77 2) 30/77 : 2 3/11 = 3 + 2*11.11 = 30/77 : 25/11 = 30/77 * 1125 = 330/1925 = 6/35
