What does this model represent? -15+ 3+ 3 + 3+ 3+ 3= -15 + 5 (3) = 0
A. 15 divided by 3
B. -15 divided by 3
C. 3 . —5
D. —15 divided by —5
D. —15 divided by —5
To understand what this model represents, let's break it down step-by-step:
Step 1: -15 + 3
The sum of -15 and 3 is -12.
Step 2: -12 + 3
Adding 3 to -12 gives us -9.
Step 3: -9 + 3
The sum of -9 and 3 is -6.
Step 4: -6 + 3
Adding 3 to -6 gives us -3.
Step 5: -3 + 3
The sum of -3 and 3 is 0.
Therefore, the model demonstrates that by repeating the addition of 3, starting from -15, six times, we reach a final result of 0.
The correct answer choice that represents this model is:
A. 15 divided by 3
