Mee im dieing i need i'm very stupid and idk these things and if u could explain to me how i can add fractions

So what you do for example  
1        3
-   +    -   =1 and 1/4 
2        4  hope this helps good luck

You just need a common denominator.
#2 - 4 x 3 = 12. So use 12 as your common denominator.

All you have to do is find the LCM (lowest common multiple).
Multiples of 4 are 1, 2, 4, 8, 12, 16 etc
Multiples of 3 are 1, 3, 6, 12, 18 etc
So find the lowest number that is the same for both. 12. And then multiply 4 & 3 by each other.

1/4 x 3 = 3/12
2/3 x 4 = 8/12

Multiply the denominators to get the same number for both

For that question the answer would be 3/12, 8/12
(The / is a fraction line)
