We now have all four operations for fractions. Table 1.3 summarizes fraction operations. Table 1.3 WebWe had to change the fractions so their denominators were the same. To do that, we found the lowest common denominator, or LCD. We can only add or subtract fractions if they have the same denominators. So we'll need to find the lowest common denominator before we add or subtract these fractions.
