    TThe ratio of boys to girls is 12 to 16, 12:16 or 12/16 (all different ways this can be written).  The fraction form 12/16 can be reduced by dividing by the greatest common factor.  Both 12 and 16 are divisible by 4, so the reduced fraction is 12/4 over 16/4 = 3/4.  In other words, there are 3 boys for every 4 girls in the class.

    The ratio is written as 12/16.  To put in simplest form you must determine what number can be evenly divided into both the top number 12 (numerator) and the bottom number 16 (denominator).  That would be 4

    12 / 4 = 3

    16 / 4 = 4

    So the ratio in simplest form would be 3/4

    the ratio is 12:16 and u just divide both the numerator & denominator 'till u can't divide them equally anymore to get the simplest form.

    Hope that helps!
