A fraction is only "dissimilar" in relation to another fraction. It cannot be "dissimilar" to a whole number. A fraction is added to a whole number by either of two means. 1. Express one adjacent to the other to make a mixed number

__Example__: 1 + 3/4 = 1 3/4 2. Express both over a common denominator, usually the denominator of the fraction. Then add.__Example__: 1 + 3/4 = 4/4 + 3/4 = 7/4
