If there are 12 black pens and 10 blue pens, write the ratio of black pens to total pens as a fraction in simplest form

Hey there,

Ok 12 black pens and 10 blue pens.  The ratio of black/total is then 12/(10+12) = 12/22.  To find the simplest form, you have to divide both of those numbers by their greatest common factor, which is 2.  Then, your fraction of black/total is 6/11.
