Solve: Finding the Sign of -4/(-0.4) ÷ -1.7 in Mathematics

We will only look at whether the number is negative or positive.

In other words, the exercise looks like this:

$-\times\frac{+}{-}:-=$

If we solve the exercise from left to right, we'll first multiply the fraction:

$-\times\frac{+}{-}=$

Since the numerator of the fraction is positive and divides by the negative denominator, the resulting fraction will be negative.

Now the remaining exercise is:

$-\times-:-=$

If we multiply minus by minus, we'll get a positive number:

$-\times-=+$

Now the resulting exercise is:

$+:-=-$

Therefore, the sign of the exercise result will be negative.
