Anit [1.1K]

Given that Nicholas has a 115 fantasy and science fiction books which is 46% of his collection.

Now we have to find what is total number of books in his collection.

Let number of books in Nicholas collection = x

then number of fantasy and science fiction books = 46% of x = 0.46x


We already know that he has 115 fantasy and science fiction books, so both values will be equal and give equation:

0.46x=115

now we can solve this equation to find the answer.

x=\frac{115}{0.46}

x= 250

Hence final answer is:

Nicholas has 250 books in his collection.
