Maka

$table attributes columnalign right center left columnspacing 0px end attributes row cell 4 over 9 divided by 1 fourth end cell equals cell 4 over 9 cross times 4 over 1 end cell row blank equals cell fraction numerator 4 cross times 4 over denominator 9 cross times 1 end fraction end cell row blank equals cell 16 over 9 end cell end table$

Jadi, 4 over 9 divided by 1 fourth equals 16 over 9 .

$table attributes columnalign right center left columnspacing 0px end attributes row cell 5 over 15 divided by 7 over 8 end cell equals cell 5 over 15 cross times 8 over 7 end cell row blank equals cell fraction numerator 5 cross times 8 over denominator 15 cross times 7 end fraction end cell row blank equals cell 40 over 105 end cell row blank equals cell fraction numerator 40 divided by 5 over denominator 105 divided by 5 end fraction end cell row blank equals cell 8 over 21 end cell end table$

Jadi, 5 over 15 divided by 7 over 8 equals 8 over 21 .

$table attributes columnalign right center left columnspacing 0px end attributes row cell 3 over 16 divided by 2 over 9 end cell equals cell 3 over 16 cross times 9 over 2 end cell row blank equals cell fraction numerator 3 cross times 9 over denominator 16 cross times 2 end fraction end cell row blank equals cell 27 over 32 end cell end table$

Jadi, 3 over 16 divided by 2 over 9 equals 27 over 32 .
