9-digit 1:2:3 ratio sequences Using all digits from 1 thru 9 ( each just once ) to form a sequence of 9 numbers, how many sequences of three different 3-number-groups can you find that are in ratio of 1:2:3. Here is an example of one sequence 192 : 384 : 576 whereby 384 is two times 192 and 576 is three times 192 Congratulations to these solvers as of FOUR solutions found by Niven Brown, Kim Famik, Clara Ferrando, Albert Frank, Ioannis Garoufalidis, Joshua Green, Jeff Hamburg, LW Luk, Valmai Osborn and Uldis Strautins. |
