False for every rate there is only one unit rate. there is however more than 1 rates for one unit rate. for example 4/2 would have 2/1 as a unit rate but 2/1 can have 4/2 and 8/4 as rates and so on. hope this helps good luck!

icang [17]

Answer:

The number of fiction books is <u>500</u> and non fiction books is <u>1500</u>.

Step-by-step explanation:

Given:

Total book library contains = 2000.

There are 3 times as many non fiction books as fiction books.

Now, to determine the number of non fiction books and fiction books.

Let the fiction books be $x.$

And the non fiction books be $3x.$

Total books = 2000.

Now, to get the number of non fiction books and fiction books we put an equation:

$3x+x=2000.$

$4x=2000.$

Dividing both sides by 4 we get:

$x=500.$

Fiction books = 500.

Non fiction books = $3x=3\times 500=1500.$

Therefore, the number of fiction books is 500 and non fiction books is 1500.
