Today we will divide with decimals.

Divide= Divide means to break a number of items into groups that have

the same amount.

You work all day with three other friends and you employer pays you 160.00 dollars for

the day. You must now divide the $160.00 evenly between the 4 of you. How much

does that equal?

$40.00 each!

You have now just divided!!!!
