Homework

Thank you DeBorde Family for your comments,

First of all, we are taking this week off of homework. As for the more difficult problems on the multiples of 10, 100, 1,000 page here is how to solve one of the problems.

#8) 240,000 / 4,000
First we can simplify the problem by crossing off the zeros that each number has in common
4,000 has three zeros at the end... so we can take off those three zeros and three zeros off of the 240,000
Now we have 240 / 4
Next I can use what I know about multiplication
4 x 6 = 24 so 4 x 60 = 240
if 4 x 60 = 240 then 240 / 4 = 60
240,000 / 4,000 = 60

#15) WE need to Estimate each quotient
17,400 / 92
First we change 92 to a FRIENDLY # like 90
Then we change the dividend 17,400 to a number COMPATIBLE with 90
9 x 2 = 18 so we can change the 17,400 to 18,000
Now we have 18,000 / 90
Then we can use multiplication to help solve division
90 x 2 = 180
90 x 20 = 1800
90 x 200 = 18,000
18,000 / 90 = 200
(How close is our estimate 17,400 / 92 = 189.13)

Hope this helps with the homework.
