Find the Missing Symbol in Sequence: -0.9:-9:-4?0

Question

Fill in the missing symbol (?):

$-0.9:-9:-4\text{?}0$

Note that in the first step we are dividing a negative number by a negative number:

$-:-=+$

This means that the exercise can be written as follows:

$+:-?0$

Now we are dividing a positive number by a negative number:

$+:-=-$

Therefore, the final exercise will look like this:

$-?0$

We are left with a negative number, meaning a number less than zero.

Therefore, the answer is:

$- < 0$
