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

    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

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

    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

    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?

    Least common denominator is the abbreviation.

    You need the LCD, not the LCM right?

    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

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

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

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

    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..

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

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

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

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

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

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

    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
