You cannot add fractions that have different denominators until you identify a common denominator that they can share. The best way to do this is to find a multiple that they both share. If the numbers are small, simply multiply them against each other to find out what the common denominator is going to be.
Example: 3 x 4 = 12. This means that we will use 12 as the common denominator for our equation.
