65 : 100 and 13 : 20

Step-by-step explanation:

It's asking for the ratio of girls to total students, meaning your ratio should look like this:

girl students : total girl students + boy students

so, if you plug the numbers, it should be:

65 : 65 + 35

65 : 100

Then you simplfy to get the most exact ratio possible, which would be:

65 : 100 and 13 : 20
