Answer:
Step-by-step explanation:
The same array can represent both multiplication and division because for multiplication you count all the dots in the array. For division you do the array backward. 81÷9= ?. For this problem you would draw out 9 dots, then adding rows you would count to 81. Once you got to 81, the amount of columns you have is your answer. So for that problem your answer is 9.
