Question

find a rational number between -3 and -2

Answer 1

We can see no rational numbers between -3 and -2.

So, let's multiply the numbers by any number greater than or equal to 2/2.

So,

-3*2/2=-6/2.
-2*2/2=-4/2.

Now, we can see that -5/2 is a rational number between -3 and -2.

We can find more numbers multiplying -3 and
-2 by 3/3 or 4/4 and so on.
