The word Quotient is the answer to the division question.
If you have 6 dollars and you need pens for scrap booking that are 0.40 cents each?
We used 10x10 grids to solve this problem.
I did my grid like this :
(every colour represents a new type of pen.)
The number you could get with $6 is 15 glitter pens.
If you look at the two first pictures
= 5 glitter pens. and this is equal too $2 , 2 goes into 6 3 times. So, multiply the 5 x 3 = 15 glitter pens.
Now if you estimate, and make it an EASIER question, this is how you do it.
.40 round it off to 0.50 and round it to 2.
+2 - 2
6 - 6
8 - 8
10 - 10
12 - 12
Where to put the decimal?
Round 3.6 to 4.
Now, change the question to a multiplication question.
Now divide the 16 by 4.
4 is nearer than 42. So put the decimal between the 4 and the 2.
This is a lady showing you how to divide decimals, if you need any help.

One thing the video brought up is that even though it looks like the answer is 3,864 you have to consider the numbers after the decimal point that hold value. In the equation the digits .1 and .4 are after the decimal point so you move the decimal point two places to the left. You will get 38.64 instead of 3,864.
I'm sorry about the fact that my keyboard doesnt have a divide button on it.
Remember: Math Links page 57-59 numbers 3-21 isn't homework
Here's an excellent link to a website that explains the concept of multiplying decimals well.

What is the total when estimating?
1.69 x5= Tax is included.
Younger sister says it only costs 5 bucks.
Older brother says it only costs 10 bucks.
What are they thinking, how are they estimating?
Younger sister is thinking Under estimating, just 1.00x5= $5.00
Older brother is thinking Over estimating, 2.00x5= $10.00
Where do the decimals go?
2.2 x 1.8= 3960
Where do the decimals go here?
3.9 x 5.8= 22620
Is $9.00 enough and prove it.
2.57 x 0.45= 118220
Pronghorn: 58kg Dall's: 1.5 times as much as a pronghorn.
How much does Dall's weigh?
Approximate: 90kg. 60x1=60 kg.
90 kg. (In between the two weights.)
46x2.5 = 64x4.5 = First estimate then calculate.
Here is a video for multiplying decimals. If you click multiplying decimals it will take you to a link that explains the multiplying of decimals. Good Luck and I hope it isn't hard to understand.
Mr.Isfeld will be collecting number of the day tomorrow.
