Question

Sam read then books over the summer four were nonfiction the rest were fiction what percentage were fiction

Answer 1

We can start by using the formula for finding the percentage:

percentage = (part/whole) x 100

In this case:

- The part we're interested in is the number of fiction books, which is the total number of books minus the number of nonfiction books.
- The whole is the total number of books.

If we call the total number of books "T", we can write:

- Nonfiction books = 4
- Fiction books = T - 4

So the whole is T:

- Whole = T

Now we can substitute these values into the formula:

percentage = (part/whole) x 100
percentage = ((T - 4)/T) x 100

Simplifying this expression, we get:

percentage = (1 - 4/T) x 100

So the percentage of fiction books is given by this expression. We don't know the actual value of T, so we can't determine the exact percentage, but we can make some general observations:

- If T is very small (e.g. T = 5), then the percentage of fiction books will be close to 80% (i.e. 1 - 4/5 = 0.2 or 20%, so 100% - 20% = 80%).
- If T is very large (e.g. T = 100), then the percentage of fiction books will be close to 96% (i.e. 1 - 4/100 = 0.96 or 96%, so 100% - 96% = 4%).
