Hey there :)
We need to change all fractions to have a common denominator
Lets see:
Multiples of 2: 2 , 4 , 6 , 8 , 10 , 12
Multiplies of 3: 3 , 6 , 9 , 12
Multiplies of 4: 4 , 8, 12
The common denominator is 12
2 x 6 = 12
3 x 4 = 12
4 x 3 = 12

=
We need to add the numerators while keeping the same denominator
