c) $table attributes columnalign right center left columnspacing 0px end attributes row blank blank cell 1 over 8 end cell end table$

a)
$table attributes columnalign right center left columnspacing 0px end attributes row blank blank cell fraction numerator 3 cross times 25 over denominator 4 cross times 25 end fraction end cell row blank equals cell 75 over 100 end cell row blank equals cell 0.75 end cell row blank blank cell therefore 0.75 cross times 100 equals 75 percent sign end cell end table$

b)
$table attributes columnalign right center left columnspacing 0px end attributes row blank blank cell fraction numerator 2 cross times 20 over denominator 5 cross times 20 end fraction end cell row blank equals cell 40 over 100 end cell row blank equals cell 0.4 end cell row blank blank cell therefore 0.4 cross times 100 equals 40 percent sign end cell end table$

c)
$table attributes columnalign right center left columnspacing 0px end attributes row blank blank cell fraction numerator 1 cross times 125 over denominator 8 cross times 125 end fraction end cell row blank equals cell 125 over 1000 end cell row blank equals cell 0.125 end cell row blank blank cell therefore 0.125 cross times 100 equals 12.5 percent sign end cell end table$
