Pembahasan

Ubahlah pecahan desimal tersebut menjadi pecahan biasa, kemudian ubahlah tanda pembagian menjadi tanda perkalian dan baliklah pecahan kedua kemudian kalikan pembilang dengan pembilang, penyebut dengan penyebut seperti berikut ini:

begin mathsize 14px style table attributes columnalign right center left columnspacing 0px end attributes row cell 4 comma 56 space colon space 0 comma 3 space colon space 1 comma 9 end cell equals cell 456 over 100 space colon space 3 over 10 space colon space 19 over 10 end cell row blank equals cell 456 over 100 cross times 10 over 3 cross times 10 over 19 end cell row blank equals cell fraction numerator 456 cross times 10 cross times 10 over denominator 100 cross times 3 cross times 19 end fraction end cell row blank equals cell fraction numerator 45.600 over denominator 5.700 end fraction end cell row blank equals 8 end table end style       

Dengan demikian begin mathsize 14px style table attributes columnalign right center left columnspacing 0px end attributes row blank blank 4 end table table attributes columnalign right center left columnspacing 0px end attributes row blank blank comma end table table attributes columnalign right center left columnspacing 0px end attributes row blank blank 56 end table table attributes columnalign right center left columnspacing 0px end attributes row blank blank space end table table attributes columnalign right center left columnspacing 0px end attributes row blank blank colon end table table attributes columnalign right center left columnspacing 0px end attributes row blank blank space end table table attributes columnalign right center left columnspacing 0px end attributes row blank blank 0 end table table attributes columnalign right center left columnspacing 0px end attributes row blank blank comma end table table attributes columnalign right center left columnspacing 0px end attributes row blank blank 3 end table table attributes columnalign right center left columnspacing 0px end attributes row blank blank space end table table attributes columnalign right center left columnspacing 0px end attributes row blank blank colon end table table attributes columnalign right center left columnspacing 0px end attributes row blank blank space end table table attributes columnalign right center left columnspacing 0px end attributes row blank blank 1 end table table attributes columnalign right center left columnspacing 0px end attributes row blank blank comma end table table attributes columnalign right center left columnspacing 0px end attributes row blank blank 9 end table table attributes columnalign right center left columnspacing 0px end attributes row blank equals blank end table table attributes columnalign right center left columnspacing 0px end attributes row blank blank 8 end table end style.
