How to Change Fractions


Question: 4/2 + 2/3 = ?

First of all they don't have the same denominator, so you have to find it by finding

the denominators common factor!
2: 2, 4, 6<--
3: 3, 6<--
- Six is their common denominator!

........................................._.... _
Second, Now you write down 6 + 6 on your paper. And at the top you should have your question down.


4....2
_...._
2 + 3

Third: In your question, look how many twos are in 6, it's 3 right, so mulitply 4x3= 12 so bring that down to your new question:

12
_...._
6 + 6

Then, do the same thing to 2, how many 3's in 6, 2 right, so muliply 3x2= 6 add that to the new question =

12...6
_..._ =
6+6

WAIT! 6/6 = whole number so it'll be 1. So the answer will be 1 12/6

-Hope this helped, the picture explains better, sorry D:

  1. Great post. But the title is kind of misleading; How to change fractions? to what? Also this is more like "Adding fractions with a uncommon denominator".

  2. Good explanation but I think your answer should be 16/6
    Because 4x3=12
    2x2=4
    So it should look like this
    12/6 + 4/6= 16/6
    6/6 + 10/6= 1 10/6
    1+ 6/6+4/6=2 4/6
    Lowest term- 2 2/3
