30 : 3 = 10 - доп.множ. к 1/3 = (1*10)/(3*10) = 10/30
30 : 3 = 10 - доп.множ.  к 2/3 = (2*10)/(3*10) = 20/30
30 : 5 = 6 - доп.множ. к 1/5 = (1*6)/(5*6) = 6/30
30 : 5 = 6 - доп.множ. к 2/5 = (2*6)/(5*6) = 12/30
30 : 5 = 6 - доп.множ. к 4/5 = (4*6)/(5*6) = 24/30
30 : 6 = 5 - доп.множ. к 1/6 = (1*5)/(6*5) = 5/30
30 : 6 = 5 - доп.множ. к 5/6 = (5*5)/(6*5) = 25/30
30 : 10 = 3 - доп.множ. к 3/10 = (3*3)/(10*3) = 9/30
30 : 10 = 3 - доп.множ. к 7/10 = (7*3)/(10*3) = 21/30
30 : 10 = 3 - доп.множ. к 9/10 = (9*3)/(10*3) = 27/30
