Pertama-tama, sederhanakan perbandingan yang ada pada soal.

$begin mathsize 14px style table attributes columnalign right center left columnspacing 0px end attributes row cell A space colon space B end cell equals cell 1 1 half colon 2 1 fourth end cell row cell A space colon space B end cell equals cell 3 over 2 colon 9 over 4 end cell row cell A space colon space B end cell equals cell 6 colon 9 end cell row cell A space colon space B end cell equals cell 2 colon 3 end cell row blank blank blank row cell B space colon space C end cell equals cell 2 1 half colon 3 3 over 4 end cell row cell B space colon space C end cell equals cell 5 over 2 colon 15 over 4 end cell row cell B space colon space C end cell equals cell 10 colon 15 end cell row cell B space colon space C end cell equals cell 2 colon 3 end cell end table end style$

Kemudian gabungkan kedua perbandingan.

$begin mathsize 14px style table row cell A colon B space space space space space equals 2 colon 3 end cell cell cross times 2 end cell row cell space space space space space space space B colon C space equals space space space 2 colon 3 end cell cell cross times 3 end cell row cell space space space space A colon B colon C equals 4 colon 6 colon 9 end cell blank end table A colon C equals 4 colon 9 end style$

Tentukan A : C dalam bentuk paling sederhana!
