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!!!!

decimal numbers less than zero 0.07 0.7

This figure has an area of 3.6 units. Let’s divide 3.6 0.8 = 4.5 0.8 3. 6.. 0 4 -3 2 4 0. 5 -4 0 0

Let’s work some out together! 1 st step: First number goes inside. Second number goes outside. Second number goes outside. 2 nd step: Move the decimal pt. in the divisor all the way to the right (make it a whole number), then move the decimal pt inside the same amount. Place decimal pt. straight above on top. 3 rd step: long division (be careful to keep digits lined up). keep digits lined up). 9 0 3 0 - 0 3 1 6 - 30 1 0 2 - 10 0 4.5310.05 4.531 ÷ 0.05.... - 4 5.. 0 0 -3 2 4 0. 5 -4 0 0
