6-8.

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.

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.
