Best Answer

The easiest way is to:

- Convert the mixed numbers into improper fractions
- Make the improper fractions into equivalent fractions with a common denominator
- Add the fractions normally (add the numerators)
- Simplify the result (if possible)
- Convert any improper fraction back into a mixed number (if required)

13/4 + 11/2 = (1x4+3)/4 + (1x2+1)/2

= 7/4 + 3/2

= 7/4 + (3x2)/(2x2)

= 7/4 + 6/4

= (7+6)/4

= 13/4

= (3x4+1)/4

= 31/4

Adding one half to one fourth will give you three fourths. To find the answers to questions like these, create a common denominator and add the two together. For example, change one half to two fourths (still the same fraction, just multiply top and bottom by 2) and add one fourths to get the answer of three fourths.
