write the percent as a fraction. simplify if possible
:
per cent means part of a 100, start out by putting it over 100
;
19. {{{68/100}}}
Both numerator and denominator are even, reduce by dividing both by 2:
 {{{68/100}}} = {{{34/50}}}
Still even, divide by 2 again
{{{68/100}}} = {{{34/50}}} = {{{17/25}}} simplified as much as you can now


 20. {{{35/100}}}
Both numerator and denominator can be divided by 5 
{{{35/100}}} = {{{7/20}}};
