### Dividing decimals

Dividing Decimals

Division means to divide things into equal groups.

Quotient- answer to a division question.

You have 6\$ you want to buy fancy glitter pens to to enter the world scrapbooking Olympics. The pens are 40 cents each How many can you buy?

you can get 15 pens.

Describe a way to estimate the answer.

Round 40 up to 50 and 50 goes into 6 12 times because 50 two times = 1\$ and 12 divided by 2 is 6

Where do you put the decimal?

15.4 Divided by 3.6= 4277778

round 15.4 to 15 and 3.6 to 3 or round 15.4 to 16 and 3.6 to 4

15 divided by 3= 5

16 divded by 4= 4

both of these numbers are very close to four so we put the decimal in between the 4 and the 2 so your answer is 4.277778

4.4 divided by 0.42= 1047619

round up the 4.4 to 5 and the 0.42 to 5.0 or round down to 4 and 0.4

both those eqations equal 10 so you put the decimal between the 0 and the 4 to make 10.47

Here is a video that explains how to multiply and divide decimals.
