To add the fractions  1/2  and  1/4  get a common denominator.

Since  2  can be divided evely into  4, make the common denominator  4.

Since 2 x 2 = 4, multiply both the numerator and denominator of 1/2 by 2:

     (1/2) x (2/2)  =  (1 x 2) / (2 x 2)  =  2/4

---> 9 1/2  +  3 1/4  =  9 2/4  + 3 1/4

Now, add the whole numbers together (9 + 3  = 12)

and add the fractions (2/4  + 1/4  = 3/4)

So the answer is:  12 3/4

(When you add fractions with the same denominator together, add the numerators (2  + 1  = 3) and write this answer over the common denomintor. (Don't add the denominators together!) This is how  2/4  +  1/4 becomes 3/4.)
