Adding Fractions with Unlike Denominator




1/2 + 1/3=?

This is just like adding to fruits together
1 apple+ 1 orange= 2 fruits







To answer the question on top of the page we must find Common Denominator!



A multiple of the denominators of a set of Fractions.



Example: A common denominator for 1/4 and 1/6 is 12 because a common multiple of 4 and 6 is 12.




4- 4,8,12,16


6- 6,12,18,24

1/2 + 1/3

X2
3/6 + 2/6




You can also Cross Multiply!


1 - 4
_ X_ They should all be equal together
3 - 12

Here is a link I found for you guys to learn more about adding fractions with unlike denominators

  4. Great post, Meljohn! A suggestion I'd give you is maybe change:
    1 - 4
    _ X_ They should all be equal together
    3 - 12
    I didn't really get it. Other than that, excellent post!
