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.

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.
