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

Question

Will the exercise result in a negative or a positive sign:

$-\frac{4}{-0.4}:-1.7$

00:00 Find the result sign

00:03 Let's find what sign each number has

00:20 Positive divided by negative is always negative

00:27 Negative multiplied by negative is always positive

00:33 Positive divided by negative is always negative

00:36 And this is the solution to the question

We are only concentrating on whether the number is negative or positive.

In other words, the exercise should look like this:

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

If we solve the exercise from left to right, we must 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.

Therefore the remaining exercise is as follows:

$-\times-:-=$

If we then multiply minus by minus, we should obtain a positive number:

$-\times-=+$

The resulting exercise is:

$+:-=-$

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