Solve Division Inequality: -73 ÷ ? < 0

Question

$-73:?<0$

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

The exercise looks like this:

$-:\text{?}=$

In other words, we need to divide by a number that will give us a result smaller than 0, therefore:

$-:+=-$

$- < 0$

So the answer is $+4$

$+4$
