−412:(+31)?0
\( -412:(+\frac{1}{3})\text{?}0 \)
\( -95:-7\text{?}0 \)
\( +314:-209:-5\frac{1}{3}\text{?}0 \)
\( 0:+15:-16\text{?}0 \)
\( 0:-412.5\text{?}0 \)
Note that we are dividing a negative number by a positive number:
Now the exercise is:
Since we got a negative number, it is necessarily less than zero.
The answer is:
- < 0
>
Note that we are dividing a negative number by a negative number, therefore:
This means the final exercise looks like this:
Since we got a positive number, it must be greater than zero.
The answer is:
+ > 0
<
Note that in the first step we are dividing a positive number by a negative number:
Now the exercise is:
Now we are dividing a negative number by a negative number, so:
Therefore, the final exercise will look like this:
Since we got a positive number, it is necessarily greater than zero.
The answer is:
+ > 0
<
Let's solve the exercise from left to right:
Let's remember the formula:
In other words, if we divide zero by any number, the result will always be zero.
Now we have received the exercise:
Let's solve the exercise:
We'll remember the formula we wrote earlier, and we can see that the result is zero.
So the final exercise will look like this:
Therefore, the appropriate sign is:
=
Let's solve the exercise on the left page:
Let's remember the formula:
In other words, when we divide 0 by any number, the result will always be 0.
Now we have:
The answer is:
=
\( -12\frac{1}{8}:0\text{?}0 \)
\( +800:-4:a\text{?}0 \)
\( -0.9:-9:-4\text{?}0 \)
Fill in the corresponding sign for the following question
\( (-5)\cdot(?3)=15 \)
Fill in the corresponding sign for the following question
\( (4)\cdot(?3)=-12 \)
Let's first turn our attention to the exercise on the left hand side :
Remembering the below formula:
Since no number can be divided by 0 we are able to ascertain that the expression has no meaning.
There is no meaning to the expression
Note that in the first stage we are dividing a positive number by a negative number:
Now the exercise is:
Since we don't know whether a is a positive or negative number, we cannot determine the sign.
It is not possible to calculate
Note that in the first step we are dividing a negative number by a negative number:
Now the exercise is:
Now we are dividing a positive number by a negative number, therefore:
So the final exercise will look like this:
Since we got a negative number, it is necessarily less than zero.
The answer is:
- < 0

Fill in the corresponding sign for the following question
We must first consider what we need to multiply by a negative in order to obtain a positive number.
Let's remember the rule:
Therefore, the answer is as follows:
Fill in the corresponding sign for the following question
Let's consider what we would need to multiply by a positive in order to obtain a negative number.
Let's remember the rule:
Therefore, the answer will be:
Fill in the corresponding sign for the following question
\( (-2)\cdot(?3)=-12 \)
Fill in the corresponding sign for the following question
\( (-5)\cdot(?4)=20 \)
Fill in the corresponding sign for the following question
\( (-6)\cdot(?5)=30 \)
Fill in the corresponding sign for the following question
We must first consider which value when multiplied by a negative results in a negative number.
Let's remember the rule:
Therefore, the answer is as follows:
Fill in the corresponding sign for the following question
We must first consider what value we need to multiply by a negative number in order to obtain a positive number.
Let's remember the rule:
Therefore, the answer is:
Fill in the corresponding sign for the following question
We should first consider which value we need to multiply a negative number by in order to get a positive number.
Let's remember the rule:
Therefore, the answer is:
