Question

Explain how to model the division of –24 by –4 on a number line.

Answer 1

Answer:

Here's one way to do it.

Step-by-step explanation:

-24 ÷ (-4)

-24 is the final number on the number line

-4 means you count by 4s on the number line moving backwards.

1. Start at 0 facing forward.
2. Move backwards in steps of four units from 0 to -24.
3. Count the number of steps you took (six).

Answer: +6 (The sign is + because you are still facing forward).

Answer 2

After modeling the division of $-24$ by $-4$ on the number line, we reach to zero after $6$ steps.

What is a number line?

" Number line is defined as a straight line which represents the number at the equal interval on it on the both the side of zero."

According to the question,

Given division,

$(-24)$ by $(-4)$

As shown on the model of  number line the given division we have,

• $(-24)$ divided by $(-4)$  is perfectly divisible.
• To reach zero moves $6$ steps to the right side of $(-24)$ .
• Each step represents the movement of $(-4)$.

Hence, after modeling the division of $-24$ by $-4$ on the number line, we reach to zero after $6$ steps.
