Question

Complete the table below. Provide an answer for each integer division problem, and write a related equation using integer multiplication.

Answer 1

You need to remember the Sign Rules for Division:

$\begin{gathered} \frac{-}{-}=+ \\ \\ \frac{+}{+}=+ \\ \\ \frac{-}{+}=- \\ \\ \frac{+}{-}=- \end{gathered}$

And the Sign Rules for Multiplication:

$\begin{gathered} -\cdot-=+ \\ +\cdot+=+ \\ -\cdot+=-_{} \\ +\cdot-=- \end{gathered}$

Then, knowing those rules, you can solve the operations given in the exercise:

1. For the Integer Division:

$-36\div(-9)=4$

The result is positive because both numbers have the same sign.

Now, knowing that result, you can set up the following Related Equation using Integer Multiplication:

$(-9)(4)=-36$

2. For the second Division, you get:

$24\div(-8)=-3$

Then, its corresponding Related Equation using Integer Multiplication can be:

$(-8)(-3)=24$

3. For the next one, you get:

$50\div10=5$

So, its corresponding Related Equation using Integer Multiplication can be:

$10\cdot5=50$

4. For the last Division, you get:

$42\div6=7$

Hence, its corresponding Related Equation using Integer Multiplication can be:

$7\cdot6=42$

Therefore, the answer is:
