Answer:
729
Step-by-step explanation:
In order to solve this, you need to do the reverse operation. The question is about division, so that means we are going to do multiplication. If we multiply 9x81, we will know what divided by 9 equals 81.
9x81=729
So 729 divided by 9 equals 81.
To check this just plug the number you got back into the orignal equation:
Y divided by 9 equals 81
729 divided by 9 equals 81
