Question

Hi my daughter is having trouble with an assignment. She is asked to write in her journal how to find a common denominator? She has to construct cubes and the first problem is 1/3 and 2/12

Answer 1

ok so to find a common denominator first you need to know what a denominator is. a denominator is the bottom number under a fraction

Answer 2

so all you have to do is find the first common times that 3 and 12 go into

Answer 3

3 goes into 12 pretty easy when you times it by 4 so whatever you do to the bottom you do to the top. so it would be 4/12 and 2/12 because we didn't have to times the 12 by anything it stayes the same

Answer 4

does that help?

Answer 5

ARE you there?

Answer 6

understand. But she is not allowed to use LCM on her assignment. The problem I wrote are two different problems. Can you still help us?

Answer 7

Yes

Answer 8

LCM? sorry i havn't heard that term or i musv't forgot? sorry

Answer 9

Least common denominator is the abbreviation.

Answer 10

oh ok but isn't that what is asked?

Answer 11

I'm haven't done fractions in so long sorry. She is a fourth grader and I'm a little rusty.

Answer 12

You need the LCD, not the LCM right?

Answer 13

Yeah sorry

Answer 14

And what is the problem again?

Answer 15

She has to find the common denominator and use blocks to shade in the fraction. 1/3 is the first and 2/12 is second

Answer 16

common denominator of 1/3 and 2/12?

Answer 17

The least common denominator of 1/3 and 2/12 is 6.

Answer 18

i CAN'T DO ANYTHING!!! :'(

Answer 19

dont listen to arada he is always wrong he knows nothing about math

Answer 20

\[\frac{2}{12} = \frac{2*1}{2*6} = \frac{1}{6}\]
\[\frac{1}{3} = \frac{2}{2}*\frac{1}{3} = \frac{2}{6}\]

Answer 21

Okay does she shade in the 6 blocks and leave one blank?

Answer 22

Do you have a digital camera? If so can you take a small picture of the problem and attach it here? I'm not sure what is being asked..

Answer 23

'Your daughter'? Your lies don't fall me! This is your homework, isn't it!

Answer 24

fool* fail

Answer 25

Really it's her homework. She has a journal book and she must explain her answers.

Answer 26

So I still don't understand the question, what is she asked to do?

Answer 27

She has to explain by using model blocks or cubes and show her work

Answer 28

I'm not sure how you'd do that.

Answer 29

I'm trying to understand what the teacher is asking. Not very clear about this assignment. What do I do?

Answer 30

As I said, can you attach a picture of the problem?

Answer 31

Otherwise ask her teacher about it.

Answer 32

How do I attach the problem?

Answer 33

Once you get a digital copy of it you just click the "attach file" button and navigate to the file, etc.

Answer 34

I hate to sound dumb but do I scan the paper and attach it the computer?

Answer 35

Do you have a digital camera?

Answer 36

yes

Answer 37

Take a picture and copy the file to your computer, then use the attach button on the website to upload it.

Answer 38

Well my camera is acting up!!!! I'm so frustrated!!

Answer 39

Just ask her teacher. They're generally pretty understanding about this sort of thing.

Answer 40

Here is the part 1of the problem. It says: Draw a model that represents each fraction below. The model should look like the connecting cubes you construct. 1/3 and 2/12

Answer 41

I really appreciate all of your help. I will E-mail her teacher so she can get a better understanding on this assignment. Thank you again.
