FRACTIONS

Wednesday, November 18, 2009

HELLO PEOPLE FROM 9-06! Today for the SCRIBE POST I'm going to talk about some questions from yesterday and today. AND SORRY for any mistakes!!

So lets begin!!!

This is one of the QUESTIONS we did.

Usually we would find COMMON DENOMINATOR but for this question we don't have to because they are both the same.

Anyways after we have to find the EQUIVALENT FRACTIONS. We don't have to find the equivalent fraction for this one because we didn't have to find the denominators.

Then we have to REWRITE THE QUESTION . Then we answer the question.
















That was an example of ADDING NEGATIVE FRACETIONS.

These here are very IMPORTANT.


(-)=(-)

-(-)=(+)

-(-)(-)=(-)

-(-)(-)(-)=(+)

-(2/3)=-2/3

-(-2/3)=2/3

-(-2/-3)=-2/-3


Now i'm going to give examples of SUBTRACTING NEGATIVE FRACTIONS

The first thing you have to do is... FIND COMMON DENOMINATORS and it seem like this one already has common

So.. For this one we don't have to find the EQUIVALENT FRACTION. So will go to the next step which is REWRITE AND ANSWER.

PLEASE LEAVE A COMMENT!!!!
AND THE NEXT SCRIBE IS
RAYE FLETT..
THAT IS IF YOU DID NOT DO ONE


SEE YAAHH NEXT TIME :P

Hey guys today in class we talked about adding proper fractions. So how do we add proper fractions? I'll show you how step by step.


3/4 + 1/6


Step 1: Find a common denominator. The common denominator is 12. For those who doesn't know how to find the it, I will show you how.
Okay, so that is how you can find the common denominator.

Step 2: Find equivalent fractions.
Step 3: Rewrite the question. Now you have the same denominator you can answer it.

Step 4: Answer and simplify if possible.



So that's it. The answer is 11/12. It is already simplified. Note: When you add or subtract fractions, you only add or subtract the numerators.

Homework:
Answer these questions Mr. B gave us:

1) 3/8 + 3/4

2) 1/6 + 1/4

3) 1/5 + 1/3

4) 3/10 + 3/4

5) 1/16 + 1/8

6) 1/2 + 3/5

7) 4/7 + 3/14

8) 3/4 + 7/8

9) 1/9 + 17/18

10) 1/5 + 1/4 + 1/3 +1/2

Okay, if you're having a really bad time with those difficult questions, follow the steps so you can answer those questions easily ;)

Friday ,November 13
Today we went to the computer lab to learn more about fraction at nlvm.usu.edu
First got to Number and Operations (Grade 9-12)and then to Fractions-adding





This is somehow it is look like. What we need to do here is to find out the sum of the fractions shown. First you should rename the fractions 1/7 and 1/2 so their denominators would be the same.

Now the denominators are the same you can now add the fractions.

When adding fractions with different denominators you should rename it with its equivalent fraction to make the denominator the same.

After that we went to lumosity.com, created accounts then played some games about math.

After we leave Mr. Backe told us a homework which Show You Know in chapter 2.3.
