Explain why 8,000÷ 800= 10

Cross out the number of 0s both numbers have in common  cross out both 0s so that 800 is 8 and 8000 is 80 then divide 80÷8=10

My explanation is that the number is 8,000 and 800 so you cross out 2 zeros from the 800=8 and you cross out 2 zeros from the 8,000 = 80 you cross out the zeros because there enough pairs to cross out so after you do 80 divided by 8 is 10!!

You need to include the original coordinates of the triangle to answer this. and how much does it translate (move left right up down)
