Solve Division Sequence: -12 ÷ (-1/4) with Positive Result

$-12:-\frac{1}{4}:?>0$

Let's pay attention to the exercise on the left side in terms of plus and minus signs.

The exercise looks like this:

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

If we solve the equation from left to right, we can see that we first divide a negative number by a negative number.

This means the result we get is a positive number:

$-:-=+$

Now the remaining exercise is:

$+:?=$

Our result needs to be greater than zero, and therefore we need a positive number, in order to get a positive number in the exercise.

Therefore:

$+:+=+$

$+ > 0$

Therefore the answer is $+35$
