The numerator is the top number of a fraction, and the denominator is the bottom number of a fraction. When you add or subtract fractions the denominators of both fractions have to be the same. You do this by finding the LCD or Lowest Common Denominator. All solutions should always be written in the simplest form.

Solve each equation below first identify the lowest common denominator, solve, and simplify the answer. Write the answer for each step in the blank. Show your work.
