Determine the Division Sign: Solving -2:-1947:? > 0

Let's first tackle the exercise on the left paying particular attention to the plus and minus signs.

The exercise looks like this:

$-:-\text{:?}=$

If we solve the equation from left to right, we can observe that we first divide a negative number by a negative number, so the result will be positive:

$-:-=+$

This means that now we need to divide a positive number by an unidentified integer that will give us a result greater than 0:

$+:+=+$

+ > 0

Therefore the answer is $+3.3$
