Simplify each of the following expressions. Be sure to simplify each of your answers as much as possible. Write any answers greater than one as mixed numbers. Homework Help ✎

  • Make the fractions have the same denominator.

    Add the fractions.

  • You will follow the same steps as in part (a), except that you will subtract two thirds from three fourths, rather than adding them.

  • You can either convert these mixed numbers to fractions greater than one before adding, or you can add their parts. Remember that your answer should be expressed as a mixed number.

  • To multiply fractions, you multiply the numerators by one another to find the new numerator. The same process is repeated for finding the new denominator.
