remember that (a/b) times (c/d)=(a times c)/(b times d)
also remember that a times (b times c)=(a times b) times c therefor lets say you wanted to do 120/4 remember that 120=10 times 12 and 12/4=3 so 120/4=12/4 times 10/1=3 times 10=30
so you have 3600/9 remember that you try to get rid of the zeroes as much as possible 3600=36 times 100 3600/9=36/9 times 100/1 remember that 36/9=4 because 4 times 9=36 (mulitplication facts) 36/9=4 3600/9=36/9 ties 100/1=4 times 100=400 answer is 400
