Part:Whole Ratio

Part : Whole Ratio

There are non fiction books and fiction books in a library and the ratio of non fiction books to total books is 2 : 5. There are 20 books. How many fiction books are there?

Write the total number of parts

And the total number of books

Find the books per part

Fiction parts = total parts - non fiction parts

Number of fiction books = books per part × number of fiction parts
