Respuesta :

The Answer is 81,I am typing more because it won't let me submit if I don't type more than 20 characters.
3645÷45
45 cannot go into 3 and cannot go into 36 but it can go into 364 and it can go into 364 eight times. so 45×8=360. 364-360=4 and being down the 5 so 45 and 45 can go into 45 once so the answer would be 81. I hope this helped.
