---------------------------------------
ratio of male students to female students at a certain university is 3 to 5.
---------------------------------------

That means,  3+5=8,
Eight equal parts.

If there is a total of 10,000 students,

That is the number to cut into those 8 equal parts.
{{{10000/8=1250}}}.


You do the rest.
