Addend + Addend = Sum

Dividend / Divisor = Quotient

Factor x Factor = Product

10 x 0.1 = 1 0.2 x 0.2 = 0.4

1 x 0.1 = 0.1 0.2 x 0.02 = 0.004

0.1 x 0.1 = 0.001 1.1 x 1.1 = 1.21

0.001 x 0.1 = 0.0001 11 x 11 = 121

0.11 x 0.11 = 0.021

0.111 x 0.111 = 0.012321

0.0111 x 0.0111 = 0.00012321

Rule:

When multiplying with decimals count how many decimal places. Multiply as if the number were a whole number. Count back the number of decimal places and put in your decimal place

1.2 x 0.12

If I think 12 x 12 = 144 I count 3 decimals places in the place in the original question so then 1.2 x 0.12 = 0.144 three decimal places in the answer.

10/10=1 0.1/0.1=1

10/1=10 0.1/0.01=10

10/0.1=100 0.1/0.001= 100

10/0.01=1000 0.1 /0.0001=1000

Rule: When dividing decimals multiply both your divisor to make it a whole number. Multiply the dividend by the same amount. Divide as if it were whole numbers.

2.45/0.0015

I think 0.015 x 1000 = 15 2.45 x 1000 = 2450

I do 2450115=

Salem.. I'm My opinion You should do it..... or else......... BOOOOO

Good post Filimon. I like how you finished the blog on time, and how you put the notes from Monday's class into the blog. Next time, you should try adding some colour to make the key words stand out.

ReplyDeleteGood job, Filimon. You did a tolerable job, but colour, pictures, and perhaps a little more explanation would make it even better. I am also quite confused about this:

ReplyDelete10 x 0.1 = 1 0.2 x 0.2 = 0.4

1 x 0.1 = 0.1 0.2 x 0.02 = 0.004

0.1 x 0.1 = 0.001 1.1 x 1.1 = 1.21

0.001 x 0.1 = 0.0001 11 x 11 = 121

0.11 x 0.11 = 0.021

If I am correct, you had attempted to place them into two columns. Which was not the best choice.(Also 0.11 x 0.11 is 0.0121, not 0.021.)

If you still insist on making them into columns, just make a picture.

I also think your division question, which I think is one, is very hard to follow. Once again, if you have trouble formatting something, just make it into a picture instead.

Good job Filimon! Putting in all the information we copied down on class really makes this a very informative blog. Next time, You should try putting pictures so they are easier to understand. Like what Anabelle said, you should just make a picture of the numbers. Pictures will also make the decimals stay in one line. Lastly, try putting in colours to make important words stand out. Otherwise, Good job!
