Answer 1

To add or subtract fractions, you need to find the smallest shared multiple to use as your denominator (the number on the bottom). This is called the least common denominator. You then have to multiply each entire fraction (top and bottom) so that both of your fractions have the same denominator. Then you add/subtract the numerators ONLY and leave the denominator.
