You'll need to add together the fractions 1/4 and 5/12 to obtain the single fraction that represents the number of adults in the bleachers.
What is the LCD of 1/4 and 5/12? Leave 5/12 as it is and modify 1/4 so that it has the denominator 12. Combine the two resulting fractions.

make common denominators first... so 5/12 are men and 3/12 are women
Add the two together,
Together the bleachers are 8/12 af the way full with adults, simplified is 3/4
which means, assuming that the bleachers are 100% full, that 1/4 of the bleachers are children
