Answer: Answer is in the steps.
Step-by-step explanation:
She can number the number-line from 1 to 12 and divide it evenly by 4 and see how many groups of 4 she has . For example, starting from 1 to 4 is one jump, starting from 4 to 8 is another jump, and from 8 to 12 is another jump and that is it because 12 is the largest number,which means she has 3 groups of 4. And 12 divide by 4 is indeed 3.
