Answer:
to divide by 10, you move the number you are dividing over by one
to divide by 100, you move the number you are dividing over by 2
to divide by 100, you move the number you are dividing over by 3
example:
divide by 10, if the last number is a 0 then remove the 0
100/10= 10
if the last number is not 0 then move the last number into the decimal place
1908/10=10.8
divide by 100, if the last 2 numbers are 0 then remove the last two 0
1800/100=18
if the last 2 numbers are not 0 then move the last number into the decimal place
1948/100=19.48 or 1908/100=19.08
divide by 1000, if the last three numbers are 0 them remove the last three 0
16000/1000=16
if the last 3 numbers are not 0 then move the last number into the decimal place
19555/1000=19.555 or 19055/1000=19.055 or 19005/1000=19.005
