Mandy is trying to subtract 7 − 12, and she has asked you for help. How would you explain the process of solving the problem to Mandy, using a number line?

Answer in explanation

Step-by-step explanation:

We can use a number line to explain this subtraction.

The first thing to do is to locate the number 7 on the number line. This should be located to the right of the number line.

Then, since we are subtracting, we need to count left from the position of interest. So we will count 12 integers to the left of 7.

If things are right, we would land at -5

If it was a case of addition, we will need to keep counting right from the position of origin

47.28 or 47.2857143

step-by-step explanation:

you just divide 331 by 7 and you get that answer. ( i think so tho)
