if the ratio of the world is the same for these 9th grade boys then 2/5 of the 9th graders(we will call the total t) will not be able to distinguish red from green. number that cannot distinguish red from green we will call c and we have the number that fit this category as 14
:
equation would be .4(t)=c
:
.4t=14

ninth graders
