8.Perhatikan

$table attributes columnalign right center left columnspacing 0px end attributes row cell 4 comma 8 cross times 2 comma 8 end cell equals cell 48 over 10 cross times 28 over 10 end cell row blank equals cell fraction numerator 1.344 over denominator 100 end fraction end cell row blank equals cell 13 comma 44 end cell end table$

Jadi, 4 comma space 8 cross times 2 comma space 8 equals 13 comma 44 .

9.Perhatikan

table attributes columnalign right center left columnspacing 0px end attributes row cell 25 comma 4 cross times 0 comma 2 end cell equals cell 254 over 10 cross times 2 over 10 end cell row blank equals cell 508 over 100 end cell row blank equals cell 5 comma 08 end cell end table

Jadi, 25 comma space 4 cross times 0 comma space 2 equals 5 comma 08 .

10. Perhatikan

$table attributes columnalign right center left columnspacing 0px end attributes row cell 9 comma 6 cross times 0 comma 36 end cell equals cell 96 over 10 cross times 36 over 100 end cell row blank equals cell fraction numerator 3.456 over denominator 1000 end fraction end cell row blank equals cell 3 comma 456 end cell end table$

Jadi, 9 comma space 6 cross times 0 comma space 36 equals 3 comma 456 .
