The ratio of male students to female students at a certain university is 3 to 4. if there is a total of 8,750 students, find the number of male students and the number of female students.

The final answer is: male students= 3750 while the female students= 5000.
To come up with those answers, first, add the two ratios, wherein 3 plus 4 is equal to 7. Then, make it a fraction wherein the 7 will become your denominator. It will show up like this: 3/7 for male and 4/7 for female.
Next, multiply the two fractions by the total number of students. Let's start with the male students: (3/7)(8750) = 3750; and for female students: (4/7)(8750)= 5000. 
Note: The parentheses used between the numbers is for multiplying the two numbers.

I'm pretty sure it's b). i try drawing the functions out and b is the one that stands out or isnt a "line"
