Lets look at the info we have:-

15 biographies
15 science fiction
7 reference
11 mystery books

We know he has 15 biographies. So, lets add to find out how many books he has in total.

15 + 15 + 7 + 11 = 48
48 books in total.

So lets write our ratio:-

15 biographies
48 books in total.

15 to 48
15:48
15/48

Hope I helped ya!! xD
