Answer :
i think it would be 4/15 because science is 6/15 and fiction is 5/15
i don't need it but brainliest is appreciated
The way I would do this problem would be to find a common denominator for both of the fractions.
5/15
6/15
And then we can find out how many books there are left.
5/15 + 6/15 is 11/15
11/15 books are about science and biography, the other 4/15 are fiction.
