Answer:10.5 : 12 : 13.5Step-by-step explanation:12 ÷ 8 = 1.5 (multiply this by all of the known numbers8 x 1.5 = 127 x 1.5 = 10.59 x 1.5 = 13.5

Answer:7 : 8 : 9 = 21/2 : 12 : 27/7Step-by-step explanation:GIVEN ;                     7 : 8 : 9 = ? : 12 : ?                            7/24 : 8/24 : 9:24 = ? : 12/x : ?                                             8/24 = 12/x                                               x = 12 ×  24/8                                                    x = 36                                   therefore the other two ratio's are                                 7/24 = ?/36                                   ? = 36 × 7/24                                    ? = 21/2                                       and                                9/24 = ?/36                                ? = 36 × 9/24                                 ? = 27/2                    im not quite confident with this answer, but i hope it helps!
