2) 1000 : 8 = 125 - доп.множ. 3/8 = (3*125)/(8*125) = 375/1000 = 0,375 5/8 = (5*125)/(8*125) = 625/1000 = 0,625 7/8 = (7*125)/(8*125) = 875/1000 = 0,875 3) 10 000 : 16 = 625 - доп.множ. 3/16 = (3*625)/(16*625) = 1875/10000 = 0,1875 5/16 = (5*625)/(16*625) = 3125/10000 = 0,3125 7/16 = (7*625)/(16*625) = 4375/10000 = 0,4375 9/16 = (9*625)/(16*625) = 5625/10000 = 0,5625 11/16 = (11*625)/(16*625) = 6875/10000 = 0,6875 13/16 = (13*625)/(16*625) = 8125/10000 = 0,8125 4) 100 : 25 = 4 - доп.множ. 2/25 =...
