In order to add these fractions, you must make sure that the denominators are the same. Since one of the denom. is 4 and the other is 2, we can just multiply the fraction of 41/2 by 2. Remember to multiply top and bottom.
41/2 * 2/2 = 82/4 Now that the denom. are 4 you may now add the numerators.
82/4 + 31/4 = 113/4 if you are asked to give it as a mixed fraction then it will be 28 1/4
hope this helps
