24÷8
−24÷−8
The model represents the division -24÷-8.
What model can you use to represent 10÷0?(1 point)
Responses
10÷0 is undefined because you cannot divide by 0.
0+0=0
0−0(10)=0
0+0+0+0+0+0+0+0+0+0=0
The correct response is: 10÷0 is undefined because you cannot divide by 0.

The model represents the division -15÷-5.
What model can you use to represent 28÷−7?(1 point)
Responses
(−7)+(−7)+(−7)+(−7)=4(−7)=−28
28−4−4−4−4−4−4−4=28−7(4)=0
−28−(−7)−(−7)−(−7)−(−7)=0
28+(−7)+(−7)+(−7)+(−7)=28+4(−7)=0
The correct model to represent 28÷-7 is (-7)+(-7)+(-7)+(-7)=4(-7)=-28.
To find the model that represents 16 ÷ 4, we can work through each response option:
1. -4-4-4-4= -16:
This equation involves subtracting 4 four times. However, this result is incorrect since dividing 16 by 4 does not equal -16.
2. 16-4-4-4-4= 16-4(4)= 0:
In this equation, we subtract 4 four times from 16. However, this result is also incorrect as dividing 16 by 4 does not equal 0.
3. 4+4+4+4= 16:
This equation involves adding 4 four times. This result is incorrect as well, since dividing 16 by 4 equals 4, not 16.
4. -16-(-4)-(-4)-(-4)-(-4)= 0:
This equation subtracts (-4) four times from -16. This result is incorrect, as dividing 16 by 4 does not equal 0.
Among these response options, none of them provide the correct model that represents 16 ÷ 4. The correct answer is not provided.
